Everyone at Superpowers, trick your friends by making an object move on its own. Here's how. You're going to need five toothpicks. And what we're going to do is we're going to bend them. We're going to try not to break them in half. And we're going to do it for all five. Now, we're going to put them in this arrangement with the bend parts towards the center. And all you have to do is just add water. By adding a little bit of droplets to the water in the center, What's happening is the wood through that capillary action starts absorbing the water. This absorption of water causes the wood to expand as it swells up. That swelling up straightens out those fibers and causes these toothpicks to move.
