My daughter is going to do this for her school science fair. I think we'll do a few attempts at home just to be sure she has a good idea how to do it and what to expect. Should we use a different bottle each time or can we reuse? Also, about how much radius would you recommend for launch to safely be away from cars and the school building? Thank you, great video!
That is exciting!! You can use the same bottle each time as long as the bottle is not ruptured. The distance you should be away from the school and cars depends on the direction and strength of the wind. If there is just a light, then 50 feet should be enough but as the wind gets stronger that distance grows. Also our build of rocket is pretty light and I cannot see it doing much damage to a vehicle or building.
