Re: Popping the balloon

we just tape the balloon down and keep it covered using plastic food wrap
that sounds awsome, right now our balloon has BB's inside of it and when popped they go down a tube and pile on to a micro switch...but it only works 8 out of ten trys and I'm not comftrable with that.Primate wrote:The easiest thing is probably to hook a balloon up to a microswitch so when it deflates, it releases the switch.
Anything that has failed once during trial runs will absolutely fail at competition, at least from my experience >.<. Using weights isn't such a bad idea, though it's probably better if they're not inside the balloon. We had the balloon wedged into a piece of piping, and then suspending a weight. When the balloon popped, the weight fell and hit our syringe. It was reliable, just a pain to build. The balloon-on-microswitch was what our regional winners used, so I'd definitely recommend it over any other contraption.cypressfalls Robert wrote:that sounds awsome, right now our balloon has BB's inside of it and when popped they go down a tube and pile on to a micro switch...but it only works 8 out of ten trys and I'm not comftrable with that.Primate wrote:The easiest thing is probably to hook a balloon up to a microswitch so when it deflates, it releases the switch.
