[High Praise! to Dude! I Want That]
Yet another toy I really wish I’d had when I was a young boy dreaming of wantonly abusing the explosive forces of nature:
* Using air and water, launch a 2 liter plastic soda bottle up to 100 feet into the air.
* Great outdoor fun for picnics, science projects, business lunches, etc.
* Very, very messy and dangerous indoor fun for those same events.
[Aquapod Soda Bottle Rocket Launcher] (Viewer #125,158)

i had a very similar item as a kid. instead of a soda bottle it was a plastic rocket, with stabilizing fins and shaped like a boat tailed bullet. great fun.
I had one of those launchers as well as a lad. Wore out the pump. Man, that thing was fun. Probably get arrested using that today.
yep, I had one as well….. sooooooo cool

Yeah, I had one of those too.
We used to get similar results with 2 tin cans, a nail, and Black Cat fire-crackers.
Ah, good times!
Suspenders with a white T-Shirt? Why didn’t I think of that?!
