Instructables
Have any ping pong balls lying around? I have an idea... how about making a few easy and effective smoke bombs out of them? Everyday household materials is all you will need. Very useful for paint ball or air soft matches, or just to have fun.

Materials:

1.) Ping Pong Balls (4 or 5 is enough for one well done smoke bomb)
2.) Scissors
3.) A Straw
4.) Aluminum Foil
5.) A Lighter or Matches

Optional:
- A Drill

Preparing Time: About 3-5 Minutes

Take a Look At the Video First, and then follow the steps!!



Be Sure to check out our other instructable on how to make money that doesn't burn! Enjoy!!

Step 1: Making A Hole

So first, go ahead and Grab a ping pong ball. Grab the scissors and anywhere you'd like poke and make a whole about the width of an average pen. If you have a drill, just go ahead and drill a hole as well.

IMPORTANT, Make sure you only make 1 hole!!!

Step 2: Cutting The Other Balls into Pieces

Picture of Cutting The Other Balls into Pieces
After you've made a hole in the ball, set it aside. Now grab the rest of the balls and poke them with the scissors, but this time cutting the whole balls into pieces. It doesn't matter what size, but not too big.

Step 3: Combining the Balls

After you finish cutting the ping pong balls, go back and grab the first ball which you made a hole into. Grab the pieces of the other balls and slowly (Don't cut yourself) insert them through the hole. After you're done with that, grab a straw and cut about a 3-inch piece. Grab that piece, and insert it through the whole and push it down.

Step 4: Aluminum Foil

Now pull out the Aluminum foil, and cut a small piece (enough to wrap half a sandwich). Cover the ball with the foil, don't cover the straw, just where it meets with the ball. Make sure to cut off excess aluminum foil.

Do you know how to make a gun for this bomb?
Take a 2'' by 2' PVC pipe, attach a 2'' PVC end cap, drill a hole in the end cap, and hot glue a BBQ lighter in the hole (barrel first) . Then simply drop the bomb down the barrel the right way, and press the trigger of the lighter. :0

Do you know if food coloring will change the color of the smoke?
if you want to throw just leave the straw out and ceal off the whole by sticking in a large peice of pingpong ball into the whol so that the outer shell covers that whol wrap it in tinfoil burn and throw

HELZZ YEEAHHH, we must make a movie for school, and we used this smokebomb for special effect, f*king cool, thx mannn!!

Keep it up

Can you stick a fuse down the "chimney" of the bomb to light it instead of heating the bottom?
if i was going to do that i would add something flammable that burns kinda slow like paper

can u put pine needles instead of ping pong balls?
i understand the smoke could posibly kill you, but thats if they would actualy smoke instead of bursting into flames!
''dont try it''
WOW! that was an awesome instructable 8)
Maybe just put the pingpong pieces into something else that won't catch on fire?

um mine acted like a flame thrower.  What did I do wrong??
duh-man Goalie13 years ago
mine did 2 but i stomped it out and smoke went everywhere! fun fun fun!
Because it says burn a hole in the bottom when really you should just heat up the hottom with a lighter
Okay, thanks. I was holding it near my face, which was stupid when it exploded!!

cut up 5 balls use NO fuse just heat the botton of the foil until you get smoke, WARNING: smoke is poisonous
Why is this necasarry to cut them up? They aren't used in any other steps.
you cut up the other ping pong balls and then stuff them inside the one with the hole you drilled. and that is what is making all the smoke.......

you added the smoke in the video but not all of it

Okay someone help me out. I think I did everything right, but it took like ten minutes to light, and after it was lit it smoked for three seconds, and then it burst into flames. Does anyone know what I did wrong?
The reason everybody is asking "what did I do wrong?" is that the formula is too inconsistent. Wrong brand of balls, not enough tinfoil, too many balls, to little, too long under a flame, etc. When making an instructable I suggest the author be a little more scientific.

This didn't work just busrt into flames. What kind of Ping Pong Balls did you use? And guys don't breathe if your going to do this, it's very toxic
I really wouldn't suggest doing it at all, really. There are much safer and way more effective ways of making smoke bombs, like sugar + salt peter. Look it up on Youtube.

Me and my mate wanted to know any ideas for making this stronger (We're having trouble getting hold of potassium nitrate), we've tried just using the pingpong ball and it worked, we then tried using bits inside but it burst into flames so any ideas? btw thnx to vic for coming up with the base idea.
You can find potassium nitrate being sold in garden shops as "salt peter". Easy, cheap, awesome.
if your having trouble getting KNO3 (potassium nitrate), i believe potassium chlorate will also work as an oxidizer.(found in the shelves of a pharmacy, forgot what it's for, i'll look into that.

don't do this it is absolutely stupid, when you do it you are burning PVC plastic and iit of course generates toxic fumes that give you HORRIBLE brain damage, ping pong balls are not for smoke bombs
