Alka seltzer in space

I wanna try this but how!!!

Either go into orbit of the earth or go into a plane and fly extremly high then go into free fall and do this thing before you hit the ground

Ok where can I steal a jet... Also how do you fly a jet

With science, cause it's cool

Good response but explain how science will help me steal a jet and pilot it

I dont know... knock them out with chemicals?

Still doesn't help me fly it though

Maybe theres some pedals or something to make it go forward

Science dose not teach me how to fly a jet but it can tell me how far I can travel,how fast and how it flys but not how to
