Would you like to swing on a star? Carry moonbeams home in a jar?
How about just some plain old model rockets.
“Estes model rockets: a brief history”.
Bonus #1: “60 Foot Ultimate Matchbox Rocket”.
Haven’t had a chance to try this yet, but I plan to.
Bonus #2: “How To Make Sugar Rockets”. Specifically:
It seems like there are a lot of videos on the ‘Tube from folks trying to build their own liquid propellant engines, but I haven’t found one yet that goes from zero to complete working engine: it looks like many of them stalled out for one reason or another. If anybody knows of a good zero to finish liquid fueled rocket video (or series) please leave a comment here.
Bonus #3: One more, for Lawrence: Colin Furze demonstrates (with some help from his friends) “How to START a Pulse Jet”, like the old V-1 engine. The video doesn’t show how to actually build a pulse jet, but the comments link to some helpful resources on that subject.
