*********WARNING**********
When making the toilet bowl cleaner bomb, read the labels on the back of the toilet bowl cleaner carton. Be safe, when the bomb is prepared run a safe distance away from it. And in cleaning up of the bomb do not come into contact with the toilet bowl cleaner or any fragment of the exploded bomb. If you are a kid, DO NOT make this without your parent, or guardians help. I do not want anyone to get hurt in the making of the bomb. So just use your mind and think. And just play it safe, ok?
Now with that said get out the following things. You will need a bottle of, "The Works", toilet bowl cleaner, aluminum foil, and a two liter pop bottle.
1. First take a sheet of foil and roll it up into a long stick as long as it can, while still fitting into the pop bottle. Step one is pictured below.
2. Carefully fill the pop bottle with 2 to 3 inches of toilet bowl cleaner.
3. Take you bomb outside and insert the foil down the neck of the bottle, screw the cap on tightly, and shake it up. Quickly take the bomb and place it outside on a safe firing zone. Kick back and enjoy the blast.
4. After your bomb has exploded clean up the trash with rubber gloves on and dispose in a proper place. Below is a video clip of inserting the foil shaking it up and the bomb going off. The video is about a minute long so, enjoy.
