Step 1

Rinse out the bottle, and let it dry.   Tape it to the car with duct tape.  Use a hammer and nail to poke a hole in the bottle cap.

Step 2

Pour the baking soda into a row or a line, then roll up the tissue.

Step 3

Have a Cub Scout hold the bottle while a second Scout fills it about half or two-thirds full of vinegar.

Step 4

Push the baking soda-filled tissue down into the bottle Quickly screw the lid on tightly, and hold your finger over the hole in the bottle cap.

Step 5

Gently rock the bottle back and forth so that the tissue disintegrates, and the baking soda and vinegar can combine.

Wait a few seconds, keep your finger tightly pressed over the hole. Put your car down on the ground, remove your finger and watch your car go flying down the street!
