HOW TO MAKE A TENNIS BALL LAUNCHER

Tennis the fun way!!!

It all started one day my nephew asked me to help him build a potato gun for his school project that had to do with trajectory and distance. First I didn’t have a clue what I was doing even though I like to think I do most of the time. So I failed miserably by welding a soda can onto a muffler pipe, hey it seemed like a good idea at the time!!!

Well there was not enough room for the gases to expand so the trajectory and velocity was very low. So, I got a little help from diypotatocannons.com. They were great! They even offered to ship me a full potato cannon kit. I just got the plans.

After building the potato cannon my nephew and I learned so much about the concept that we ended up building a tennis ball launcher in the same fashion. Since the tennis ball was so much lighter the velocity increased considerably and the trajectory was shortened as well. This won my nephew first place in his class. The teacher never specified he had to use a potato he won hands down. However, the potato cannon we built with the diypotatocannon.com plans outperformed by almost double anyone elses in the class. My nephew and I had so much fun with this project we made it a regular hobby. Pumpkin launching is next after that we don’t know what to do but I’m sure we will figure out something!!! Maybe we will start building high powered catapults.

Tennis the fun way II!!!

After our school project, my nephew and I couldn’t wait to start on the next way to launch a tennis ball. So he suggested we try the catapult approach. LOL, So here I go again thinking I know it all and failing again. Our first attemp came out looking like a bucket in the middle of a WW2 razor wire barrier. The structure was sound but I had problems with figuring out how to power it. Rubber bands don’t work quite as well as I thought they would. My nephew “the brains of the operation” suggested we try what we did last time. So, I just gave it a shot and typed in diycatapults.com. BOOM, problem solved. They have a sweet set of catapult plans that show you just how to power a catapult. We took the same process and multiplied it about 10 times. The result worked perfectly. We were able to launch 15 tennis balls a distance to far for my 100 foot tape measure to record. If I had to guess I would say about 300 feet maybe. I am probably exaggerating maybe. Anyway, it was AWESOME and apparently this is the way the romans powered their catapults as early as the first century BC. So my nephew got a history lesson as well as mechanical and engineering experience. We are going to build more types of catapults and maybe a trebuche hopefully. I sure hope diy is there to help us out on this one if we need it. You never know though I may figure it out on my own “not likely”.

If you track the links furnished here, then you will reach a very useful website on catapults and from there you can collect the free plans to build a catapult. Remember that these plans are designed for all age groups and contains easy ways of building catapults. You can also see images of different types of eye catching catapults and if you see those images, it will definitely help you while building your own catapults. Getting some sort of pleasure or enjoyment with friends will be everyone’s desire and using catapult for this purpose is not a bad idea.

Recently some of my friends invited me for a pleasure trip for some sort of fun and adventurous activity. When I realized that the trip was to a forest area, I accepted their invitation and suggested them that if we played catapults in the forest, it would be both fun and adventure. Everyone agreed with me and asked me to buy those devices from any shop online or offline. I Immediately told them that there is no need to buy catapults from a shop because my daughter aged ten and studying in her sixth standard knows how to build it and she would do it for them.

Help the environment! Go for green roofs!

All of us have to take care of our environment and make sure that we are doing everything in our capacity to make the world a better place to live for everyone around us. This realization hit me only when I got an email from my brother telling that he was going to start a new business in the poultry sector and told me that he was looking for a partner and asked me if I was interested. I certainly had a lot of free time and I was all for it. We got the place and then started deciding about the chicken coops. When I surfed on the internet, I came across this website on green roof chicken coop which explained how much environment friendly it was.

Both of us decided to go for it and it was really wonderful. The coops were ready in no time as we had hired two carpenters to do it as per our plan and we also decided to pitch in and we worked really hard to build all the coops. Now the chickens are all healthy in the chicken coops that we built and I must say that I am glad I agreed to this proposal as we really have a good and upcoming business which does not pollute the world at hand.

History of catapults

pskde — Thu, 27 Aug 2009 03:24:11 +0000

Does anyone know when did catapults originate? In reality, catapults originated in China around the 3rd and 4th BC. The meaning of catapult is that it is an appliance that stores energy and releases the energy to fire a projectile. Catapults look like a big crossbow and they were nearly 8 feet tall. Over the years these crossbows became bigger and bigger and at first these were like handheld weapons called Belly-Bow and from then on it got much larger and became something like a stand crossbow. Later on that also changed, the size and shapes also changed and there were changes on how they were operated also.

Finally this has emerged into something which is mounted on a pivot like structure and it is like a swinging arm and the catapult is emerged from this, actually this does not fire the projectile, but it moves the arm holding the projectile. Thus catapults were used in the Middle Ages by the people and as these were large and huge, they were used to demolish the walls of the castle, but catapults were there even before the origin of castles. Now they have developed the catapults into various designs and these have become user friendly now and it is easier to carry too.

Raise chickens using diy chicken coops

pskde — Thu, 13 Aug 2009 18:05:22 +0000

When I was in the military, I was placed in the border, so we used to have a hard time to get anything to eat as we had to be on guard and on our foot most of the times. I usually like to eat non-vegetarian and I used to find it difficult when most of the days we had to eat vegetarian dishes although I know vegetarian dishes were more healthy, but then one day when I was speaking to my wife over the phone, she suggested this website to me and told me to refer this site on diy chicken coops and follow the guidelines.

When I read them along with my friends, we made great plans and we thought it would be a good idea to raise chickens on our own, and so with the help of the instructions provide in the website, we built our own chicken coop and finally when we finished our work, we were very pleased with ourselves. Then we bought some chicks too and we watched them grow and finally one day we had a hearty meal also and we decided that we would have many more chicken coops as that would be useful for us.

Chicken coop plans for your coop

pskde — Tue, 04 Aug 2009 15:25:52 +0000

When I lost my job due to the recession, I was really worried because I had no idea what my family was going to do for its daily needs. My friend, who used to be my colleague before he lost his job, contacted me after coming to know that I had lost my job. He told me that he was planning to start up a small scale business and asked me if I wanted to become a partner. I thought about it and I told him that I was ready to do it and I enquired him about the job. He said that we were going to build chicken coops and sell eggs and meat to the locality and the stores.

He told me that there was an initial investment involved as we had to employ a carpenter to build the chicken coops. I told him that he could start up and I would make the necessary investments. When I was browsing the internet, I saw this website and got the easy chicken coop plans which I thought would be useful for our business. When I looked through it in detail, I realized that we would be able to save a lot of money by building the coop ourselves with the plans. I told this to my friend and all of them agreed. Now, after a few months, I am really glad that I took up this business because I have been making a lot of money.

Wonderful siege weapons

Siege weapons are a lot of fun to play with and there are a lot of them and all of those weapons together in one game make it very good to play. I saw a few children playing in the park with catapults, crossbows, trebuchets, launchers and cannons. There were pretending that they were having a war and they were launching sticks and paper balls. It looked like a lot of fun and the kids were enjoying themselves thoroughly. It is also quite easy to build these weapons as all the details regarding them are available on the internet and in many other books.

With a lot of designs available on all these siege weapons, it will be very good to see many of these together. It would in fact be a very good do it yourself project because it does take some effort to build these weapons. You can collect the plans or blueprints and the necessary materials and get to work and with some practice, you will soon be able to become an expert and maybe even make your own design and become the envy of many others. Now, that is a very cool and definitely fun diy project.

Give special lectures on chicken raising and care

pskde — Fri, 17 Jul 2009 17:18:06 +0000

I used to give special lectures on different topics when ever I am asked to and once I was invited to give a speech on any topic I wanted as a guest lecturer. I was confused at first and later I decided to give the lecture. The next confusion was about the topic of my lecture. Then an idea struck me. I was giving the lecture for agricultural students and I thought that the ideal topic would be about chicken raising and care. I prepared thoroughly on the subject with the help of this website and was confident that the lecture would go well.

I went to the lecture and at the end of my class, I had such a good response and I was really glad. So many students asked me for guidance to build chicken coops and I directed each one to the appropriate website and told them all that they would be able to improve their health and also earn money through it in the future. I am also glad to say that one of those students have a flourishing business in the poultry sector and he is living his life healthily and wealthily. You can have that too if you put your mind to it and of course, this website to give you all the guidance you need.
