this is just a test run of what might happen with a 2nd stage on a water-bottle rocket. This will work because that string will be snipped at around 100 feet,(far less the expected height) so that it will be pulled and launched off the other rocket
I made this in order to test a 2 staged rocket concept to go on top of a regular 2 liter rocket that is pumped

water bottle, milk crate, string, alka seltzer

1 tape a string going counter-clockwise on the cap so that when pulled, it loosens
2 fill the bottle halfway with water
3 set bottle on milk crate or other platform
4 put alka-seltzer in there (halves are easier) usually 6 is good enough, more you are risking exploding the bottle (fun still but no launch)
5 close bottle just enough until there is resistance
6 flip bottle over
7 pull string when it stops bubbling
