A 2-stage water rocket

Hi, try see the description. Separation is after about 60 milliseconds....

I still have the feeling you would gain height by separating a little later.

Great video!

Hi,

Try read the info text. Separation is milliseconds after launch. The booster helps very little in terms of separation altitude - but a lot in terms of speed.
