Awesome website for off season side project antics. Cool projects too.

I just found this site today, and am already in the works of making a soda bottle rocket launcher device.

Why waste mentos and coke, when all I need is air & water? LOL

heh that's old Elgin.... our physics class has been doing that for years
get with the times geeze
no, really it's a lot of fun
have at it!
(be sure to post pictures of you soaked!)

Are you going to reuse the deck railing, concrete tube, and stove pipe?

Let me know if you need any of those small air storage tanks, I still have them. I also have plenty of SMC and Festo fittings if you need them. Any pnuematic stuff needed let me know because I do have some valves, vac generators, cylinders, tubing.............I'm just not sure of everything I have, I'd have to dig around in the shop in my basement.

(That 5' pnuematic cylinder isn't up for grabs though, I'm still saving that one for a Halloween display )

I have posted this before, ill search for it, but it can be done with a pump or air compressor. Very easy to do.

If you don't have an air compressor you can use a bike pump... Altitude 100-150 feet. With correct pumping timing & water amount.

Notice: I didn't put out much information on the launcher but it isn't that difficult to figure out.

with my class we used good ol' muscle and a bike pump

Why make a air and water rocket when you can make a mentos and diet soda rocket?!

LOL Been there done that, and I'm in that video.

It's going to be surpassed this weekend though *hopefully* if I get my darn launch mechanism working right.

We have an unnofficial contest brewing in CT at Sam's (230) graduation party this Saturday.

Some entries will bring the noise (Kevin's (237) cannon), and some will bring the height (Mine, Samm's(228) & Art's (228) Mentos & Coke rockets).
But all in all it'll be a very scientific day. LOL What better way to celebrate a FIRSTers graduation party right?

Hmm 166 shows off bottle rockets using air and water every year.

You're a little behind

Some of these look really cool. I especially like the LED Throwies. Imagine hundreds being thrown about in the dark.
