Make a Vacuum-cleaner Bazooka

Step 3 Lauch it and Tweak it

Launch it:

• Power up the vacuum cleaner.
• Cover the tubes' ending with the PVC-junction with the business card. The vacuum cleaner will now suck air from the other end of the PVC tube.
• Hold the projectile firmly, and insert it in the air-sucking tip of the pvc tube.
• Let go and enjoy!

Tweak it:

• If you extend the straight pvc tube, the projectile will be accelerated over a longer period. And so the projectile's velocity will increase. So extend that piece of tube!
• Add some weight to the projectile. We filled the capsule with rice, but sand might work better. Experiment to find the right weight for the projectile.

Again: Have fun! Don't shoot in the direction of living creatures, though. So be careful, too.

All I see is an unfinished Airsoft RPG Launcher. fill the egg with BBs and an m120. Stick the fuse out of the bottom of the egg. Light the fuse, and shoot the egg. Lots of experimenting with timing would be necessary, but I think the end result would be worth it.

could i make it with a 90 degree elbow piece?

Yes. The chance that your projectile will get stuck is slightly bigger, but if you choose projectiles that are a bit longer than the plastic eggs I use, it won't be a problem.

instead of a 3 way connector?

Have a look at Bloomautomatic's comment (with pics). Is that what you mean with a 90 degree elbow piece? That version works!

Hey there, I made a version of this with the kids on the weekend!! Brilliant!! Thanks for posting, it was so simple that they were able to assist with most of the construction.... absolutely ingenious!! Cheeeers!

I bet you could use a bit of tape and maybe a rubber band or two to make the index card into a self-resetting door...
