Tell us about yourself!
That's a good idea. I'll have to experiment with that. Thank you for commenting.
We are indeed :)
Thanks for the comment, I couldn't wish for a better reaction to a build :)
Yes, there is nothing like rockets, fire and explosions to get kids excited about science :)
Yes, a cheap single stage from eBay.It is also good for other experiments, like inflating marshmallows and boiling water at room temperature :)
Thanks, that is a great idea.Maybe it would also illustrate how air/smoke is pushed into the acrylic tube ? -I'll see if I get time in the weekend.
Yes wouldn't it be great to have equipment like that ! :)I only once caught a single blurry frame of an object going through the tape.
I have tried two types of packaging tape (brown and clear), and foil cut round from a big sheet. They all work, so my impression is that it is not that sensitive to type of film.Sometimes the rocket will break the tape, and sometimes the air pressure will lift the tape, before the rocket passes. You can only see this with a slow motion recording.I have experimented with two layers of film, and it sometimes work, but a single layer is most stable.Thank you for commenting,
Thanks, glad you like it.

Thank you for the clarification, I will consider that.Regards
Anyone ?The reason I'm confused, is that it says "homebrew drink-related projects" in the details, and this is one of the images of the contest:Thanks,
