Easy Ways to Launch Tennis Balls
Posted on | April 29, 2010 | No Comments
There are several ways to launch a tennis ball. One way to launch a tennis is by building a catupult. Using the mechanical means that catapults have can be a lot of fun. Of course, trebuchets are even more fun. They use counter weights and leverage to launch their projectiles. You could also launch tennis balls by using a combustion based system similar to a potato cannon.
The first way, or the mechanical means, is accomplished by making an “engine”. The ”engine” in a catapult comes from making potential energy and storing it in tightly bound rope. When the pin is pulled this turns potential energy into kinetic energy and transfers that energy from the catapult engine to the tennis ball forcing a trajectory.
The second way, or the counter weight system uses heavy objects and a lever to throw lighter objects long distances. These counter weights can out weigh the projectile by thousands of pounds giving it more range. Trebuchets are very powerful and fascinating to build and launch, no matter what the size.
And, the last way, or the combustion is probably the easiest by far. To launch a tennis ball by combustion just takes a few steps and can be made out of PVC piping and a little hair spray. If you want to get fancy you can use a grill igniter and place the wire ends in the fuel ignition chamber. this will give you a push button trigger. This will make the launcher more responsive as well as easier to handle. I built a tennis ball launcher “combustion means” and had a blast with it. I kept trying to get an optimum fuel/air mixture to maximize the distance it would fire. The best way is to use a small amount of lighter fluid and give it time to expand then fire. You will be surprised how little lighter fluid it takes to launch a tennis ball, so have fun with it and make sure to be careful.

Build catapults easily with the plans

Being an entrepreneur is not a walk around the block and it is tougher than many people imagine. The only people who would know are the people who have walked down that road. At first I was a mere spectator to my father. But now I have taken over and seeing everything from this perspective is a whole lot different. When my son came running to me, clutching free plans to build a catapult, asking me (actually pleading) me to help him out, I was rushing for a meeting and brushed him aside.
Later I realized my mistake and remembered how I felt when my father had turned down exactly the same question. I made my mind that I would sit with my son and definitely make him that catapult which he desired so much. That very night we set to work and while he told me how he got the plans from a website which a friend had suggested, I built him his catapult. He was very happy and became more so when I found a little extra time everyday to spend time with him. Somehow, I feel that this website was the reason for our relationship and I feel really glad about it.

Current catapult designs
Posted on | July 26, 2009 | No Comments
Catapults have certainly evolved from the primitive design of a simple ‘Y’ shaped stick with a rubber band tied to it to modern designs which are bigger and much more effective. When I recently went to a shop, I saw a toy with a very complex mechanism and I had no idea what it was. When I asked the shopkeeper what it was, he told me that it was a catapult. I had never seen a catapult with such a complex mechanism and that was when I realized how far technology has improved and I decided to get one for my son. But I didn’t as it was as costly as it was complex.
When I checked on the internet, I understood that there were a lot of new designs of catapults, each one looking different and more complex. But the important thing is that it basically does the same stuff, that is, throws stones or any other object that you hurl. It is easy to understand all the designs and even make them if you hit the right website. There are plans that you can download, there are books that are recommended and a lot of videos that will actually show you what to do.

Build coops very easily with these plans
Posted on | July 17, 2009 | No Comments
My aunt was a very different personality and she was also very health conscious. Once she called me with a very queer request. She told me that she wanted to acquire chicken coop plans and she asked me to get them for her. She told me of a certain place and gave me some money and asked me to buy them for her. I was surprised that plans to build a chicken coop costs such a big amount. I decided to go and enquire about the place anyway. I went to the place and found out that there was no company at that address and that was when I realized that it was a fraud.
Then I searched on the internet and found that there were many websites which I identified to be fraud. I finally came across this website that offered easy chicken coop plans for free. I got those plans and told my aunt that I got those for free and gave the plans for her chicken coop and also returned the money back to her. She was delighted and thanked me for my good thinking that saved her a lot of money. I also helped her build the coop for her and now she is as healthy as ever.
Inaugurate seminars on the topic of chicken raising and care
Posted on | July 10, 2009 | No Comments
Recently an owner of a big poultry farm came to my veterinary college where I am working as a professor and told me that his farm was conducting a three days class on chicken raising and care to those who are planning to start their own chicken coop. Then that gentleman invited me to inaugurate that seminar and also requested me to give a lecture on chicken coop and how to run it successfully. Even though I used to avoid such seminars, I accepted the invitation because the owner of the poultry farm assured a handsome amount as donation to the welfare of the college.
I know that giving a lecture on the topic of chicken raising and care will be easy for me but to give a lecture on how to run it successfully needed some preparation on that subject. So I decided to visit the chicken coops website, a site with latest details on this topic, to collect some useful information. Actually I came to know about this website from one of my students who was running a medium scale chicken coop in his spare time by following the instruction collected from the above website. I also got some latest information from this site which helped me a lot while giving the lecture.
