how to make a toothpick move by Andrew Z and Chegowara H

First get a bunch of toothpicks you will also need to get a cup of water and a eyedropper with a whiteboard marker.Next you will need to break the toothpick in half then mark with the whiteboard maker the two ends of the toothpick.Finally add 2 drops of water and wait for it to expand out also wait 10sec to mark it and then you will see how the toothpick moves thank you Andrew Z and Chegowara H
