JM1971 Posted March 3, 2014 Posted March 3, 2014 (edited) Technique could be used to fire stuff with a Lego pneumatic cylinder, some of these cannons can fire a ping pong ball at mach 1.4 which can make a hole in a table tennis racket, I dont have any pneumatics to test it but you could use one cylinder to pull the air out another and then use a switch to let the air back in to fire a little ball some distance.

Doc_Brown Posted March 4, 2014 Posted March 4, 2014 "there is no money that could get me to stand in front of this thing" LMAO. I'm not sure if this is possible, hehe. How would you build a vacuum? I remember as a boy firing flex from rigid hose. (Hence why I have no flex left) If memory serves me there was large pumpy thing for lego space sets many years ago. That might be an option! Quote
JM1971 Posted March 4, 2014 Author Posted March 4, 2014 (edited) They are also good at squirting water Mythbusters series 13 episode 8 is what to watch for more info, there is a lego vacuum pump on youtube and you would just need a splitter to suck the air out the the top and bottom of a cylinder and to fire just pull the hose on the bottom. and video of it .

Balrog Posted March 4, 2014 Posted March 4, 2014 We already have the equipment to build a pressure level and one could probably come up with a solution of Technic parts that create a vacuum. But I wonder if one can build a proper launch rail and pressure chamber that are actually air tight enough. We'll see. Perhaps one of our geniae here will come up with a solution Quote
