In this instructable I will be showing how to make a smoke bomb. These are relatively easy and can take about 10-15 minutes to make depending on how fast you are.
As for the chemical reactions that are occurring when the smoke bomb is being lit, the plastic from the ping pong balls release dioxin after the chlorine and the hydrocarbons are heated.
* It is recommended that you stand a good distance away from the smoke bomb after it is lit to not absorb much of the smoke.

Ok, now we can continue! :)
Step 1: Materials
For the materials, you'll need the following:
1) 5-6 ping pong balls
3) Little bin or container
4) A piece of tin foil
5) A pencil or pen
6) Lighter or matches
7) A cheap clothes hanger (optional)
Step 2: Cut the ping pong balls
This is the most tedious and time-consuming step... cutting the ping pong balls.
Although it may sound easy, it might take some time.
First, take one ping pong ball and cut a hole in it about 1 to 1.5 cm in diameter. (Try to make it as circular as possible)
Then, take the other 4 or 5 ping pong balls and start cutting them into the container or bin in little pieces that can fit into the ping pong ball's hole. If they're too big to fit in the hole you might have to go back and cut them a little more to make them fit.
When you're at your last ping pong ball, cut one piece that's a little bigger than the hole (too close up the hole from the inside).
Once you're done cutting the ping pong balls, take the little pieces and stick them in the hole in the first ping pong ball. Then once all the little pieces are in, take the bigger piece and squish it in the hole and then move it around to close it up from the inside.
The second picture is the one with the bigger piece of a ping pong ball covering the hole in the first ball.
Step 3: Wrapping it up
Now that you have a ping pong ball that's closed off with many more little pieces of other ping pong balls inside it, it's time to wrap it up.
All you have to do is take your pencil, stick it facing up from where the hole in the ping pong ball was, and wrap a piece of tin foil around the pencil and the ping pong ball. It should look like one of those mallets or drumsticks with the balls at the end to hit those really big drums (i'm not sure what the exact name is).
Once it's all wrapped up around the pencil and the ping pong ball, take out the pencil, leaving an airway for the smoke to get out. Now it should be sort of like a straw with the ball at the end.
Step 4: Almost done! (optional)
Now, for the final step of actual work, take your clothes hanger (if you have one) and lay it done flat on a surface.
Then, bend the clothes hanger directly down the middle of the "triangular" part of it to make it sort of resemble a swan.
Lastly, bend the "hook" part of it so it is parallel to the base of the "swan-like" triangular part or so it is parallel to a flat surface.
Now you're ready to light it!
Step 5: Testing
Just place the wrapped up ping pong ball on the flat hook in the clothes hanger (or just hold it with some pliers or something) and light the bottom. As soon as some smoke starts to come out, go somewhere else (DON'T STAND RIGHT NEXT TO IT!!!) and watch it from a distance.
In case you were wondering, the straw part faces up! :) Here are two videos of it in action:
