Update: Wednesday 7:18 pm
After many launches out in the front yard, the I found the smaller the water balloon…the longer the distance. I’ve also pitched up the front end and added a second bungee cord. maintaining the throw of the arm, but raising the trajectory and giving a little more oomph…. the result. 45’ 5”.
one post design modification is that the crossbar needs to be beefier. I broke 2 in distance trials today.
Look for the Launch-o-Matic 1.0.1 inthe days to come.
for all you highfalutin, in it for the arte, got all the best equipment, practical things like kitchens, armoires and cutting board makin’ “real” woodworkers…
From the guy who brought you the Left Handed Pencil Holder…
The Water Balloon Launch-o-Matic 1.0.0
This can come in handy when we have water wars with the McCoy’s across the street. The down side is that is so small that it doesn’t fire all that far maybe 30 feet.
It’s a great summer project, and it took the sum total 1 hour, a 2×4, a 2×2 and a few screws, glue, eye bolts, a bungee cord and a 6 year old constantly saying “is it done yet, is it done yet?”
Seriously, I’m going to modify it from the band powered to a Torsion powered catapult. If I can get a water balloon 50 feet with enough velocity soak my neighbor, I’ll be happy.
Unfortunately my 10 year old could not time the shutter on the camera to get the balloon leaving the contraption…maybe next time.

lol, looks fun. Maybe you can tighten the tie down some to give it more resistance when you pull it back. That way it will shoot farther.

You need to add a remote release. That way you can get unsuspecting folks strolling on the sidewalk!!

I’d guess that 30 feet is just about far enough to get you into trouble.

Nice! I’ll bet you are a good dad and the neighborhood kids love you too.
If you remove the back cross member you can get added pull back distance on the throwing arm. Maybe add another bungeee or 3 and lengthen the throwing arm. If you use a “springy” wood like spruce maybe it would add distance?
Cant wait to see the torsion bar apparatus

Have you tried fruit yet? Overripe is always best – that way it optimizes blast radius on impact. Now of course the next level of devious to this would be to shove an M-80 into the projectile and attempt to time for air bursts.
Wait – was that in my out loud voice? I mean – hey we’re all adults here make sure you all play safely!

Gettin the range isn’t the hard part…the hard part is being able to hit a moving target while he’s mowing his lawn! Good luck!

Maybe if you got on your roof, just over the peak where you wouldn’t be seen, you could get more distance.
As for moving targets, sometimes close will get the proper reaction. Especially with overripe fruit.

Hey – I’ve got a 2×4 and a bungee cord…
What modifications would I need to make specifically for operation by a right-handed person?
This looks like a lot of fun. Thanks for sharing.

just saw this, so cool…reminds me of when i had to make a catapult in 7th grade physics, my dad helped me and he is like tim the tool man when it comes to preparation….the goal was to shoot a Ping Pong ball the farthest, somehow he thought a GARAGE SPRING would be the best (one of those super thick short ones haha)...well, it didn’t “throw” the ball very far, but it threw a 5 lb rock about 30’ and jumped off the ground as you hit the trigger! haha good times
