What Happens When You Mix A Car, College Project & A Ping Pong Ball!!

[scottish-sr]

So as part of our college course, we have to design and manufacture a device that will fire a ping pong ball 10 metres (30 feet) for less than £10.

This is what we came up with to the cost of £5. A Hyundai Accent on 3 cylinders, an O-ring attachment and long bit of pipe.

Works so well we made a video.

Will require quicktime to watch.

Yeah I forgot to mention, theres a nice red Micra right at the end of the video. Its mine!!

Long tube same diameter as the ball making sure there is no gaps round the edges
block one end off witha small chamber - put a hole in it, insert lynz can and charge it up.. 2 wires into it - make it go boom - ball will fly...

that sounds good Dusk, have you done that one?

we done similar task at uni for first year project, it was a potato cannon...

copied the instructions from... http://auto.howstuffworks.com/engine2.htm

couldnt get it to work

Tells you to use petrol - I certainly wouldnt. (petrol would explode too violently and may stay alight in the chamber)
Looking at the diagram you use a whole potato, i wouldnt (you force it into the potato to create a seal then push it down the barrel)
I havent made one, but a guy brought a tiny one into collage that fired plastic bricks - but he used areosol

We could do that, but its to fire a certain distance and we have to do risk assesment and its to be safe etc etc etc.

That way sounds fun though.

Its smaller than a potato cannon and you wont get much recoil so you could mount it to a base and fire remotely with safety..!

Could be a possibility, although we have to fire 3 seperately and reload it without going near it.

It works fine for me mate, right click and save target as. You also need quicktime or a media player that will play 3gp files.
