launch a water filled tennis ball ??????

Unread postAuthor: Captchipahoy » Wed Apr 10, 2013 3:04 pm

OK I am a newbie at this. I love blowing up stuff and firing stuff.

Here is what I want to do
3 blocks away from my home is a water tower I want to hit. With a tennis ball. I figured water filled it may work

I have collected and assembing a u shaped air chamber, 4" copper, 42" legs, 18" center, with 2" up, screwed into the bottom of a 90 degreee 2" sprinkler valve, and this into a 2 1/2" PVC barrell 5 ft long.

At 100 PSI do you all think it will travel 450-500 ft and up 150 ft ??

Really would like your opinions on this

this is by far the coolest, and most daring thing I read on the forums lol.... I dont think 100 psi will cut it, but dont fill the tennis ball with water.

My opinion is to use your own property as a target, and not shoot at the local water tower. We don't condone that sort of thing here.

I wonder how much deeper the ocean would be without sponges.
Right now I'm having amnesia and deja vu at the same time. I think I've forgotten this before.

Agreed, don't want to pour water over (inject into?) your plan but shooting at a water tower presumably not on your own property is of dubious legality, even if you didn't cause any damage.

Also, if you're shooting over 3 blocks, there's a good chance you will hit something which you never intended to hit, with possibly fatal consequences. Imagine the ball bounces off and hits a child in a stroller...

You all are right. Of course I do not wish to discuss or do something against the rules of the forum.

As for water tower, it is in a warehouse district, just large buildings, big roofs, etc. And I play on Sundays, no one around. And why the water tower, just a nice big target to go for.

Over the years we have done the wire nut blow guns, fill the water jugs with gas, propane bombs, just general crazy stuff. For 4th of july we always make a full size paper mache dummy, dress him up as uncle sam
and throw firecrackers and m-80s at him till he catches fire and is gone, we make Creamora fire pots, etc.

What do you want from a bunch of 50 year old kids :)

Don't lob water filled tennis balls into areas of building. There are people about and things that can get broken.. Don't become a reason spudding becomes illegal.

As an fyi, water filled tennis balls do fly further. I know this from lobbing them into a reservoir and having a friend in a boat retrieve them.

This doesn't sound like a good idea to me.
Imagine something like this hitting a person..

FYI, this was a rotten apple shot at an empty soda bottle at 87 PSI.
Imagine this hitting someone's head.
A water filled tennis ball will do even more damage

Apple vs 2X6 plank. These sizes are dangerous.
