Prepare:

1. 2 cups with little alcohol or water.Note: the water level on the 2 cups must be equal.
2. 2 matches.

Perform:

Place 2 cups and 2 matches as shown in the picture above. And what you will do is make two matchsticks touch each other without touching the match or cup of water.

First, put two glasses of water together. Dip your finger into a glass of water without a match and rub the cup as shown below.

Please be patient, after a while the magic will happen.

Decipher the magic tricks

When you rub your mouth with wet hands, the sound will sound quite uncomfortable. Sound or sound waves will travel in the air. At that time, the water inside the glass of 2 matches will have resonance phenomenon, vibrating into glass.

This vibration causes two matches to move and gradually touch each other.

Too simple, isn't it? You can perform this simple magic show to perform happily with friends and relatives, surely you will become the "star" in their eyes. Good luck.
