Rocket Engine Underwater

0

When I was a kid I loved launching model rockets.  I spent many hours building them from kits, and wrapping paper tubes, and newspaper, and one even from a cardboard tube that a rug was in.  That was a fun one, we put an “F” type engine in it, there was so much black smoke it was crazy.

I’m not sure why, but this video experiment of igniting a model rocket engine which is fully submersed underwater is pretty ace.

I think my favorite parts are the beginning of ignition, when the bubble is pulsating out.  That’s pretty neat.  Someone who is an actual Rocket Scientists can tell me why it does that.  And the last bit, right when the parachute charge pops and bursts the glass.
