Here's an opportunity to impress your friends. Challenge one of them for a soda by saying that you can make a robot hand. Many wouldn't believe you; some might even swear that robot hands aren't in your league. Little will they know that making robot hands is a common school project that can be done with materials you already have at home.

Things you need
- 2 sheets of paper
- 1 pencil
- 5 straws
- 1 tube of silicone caulk
- 3 feet yarn
- 2 sheets of cardboard
Put your hand on a piece of paper, then trace your hand's outline. Mark the areas of your fingers that bend; these will be the joints. Draw a diagram of where you'll place your straws. Start from the fingertips and work toward the wrists. Cut strings to the length of the thumb and fingers.
Cut the hand outline out; then place it on the sheet of paper, drawing side down. Squeeze caulk onto the straw outlines; work from the fingertips to the wrists. Cut five pieces of yarn out and place them on the caulking outline. Lay one end of the yarn on the bottom of the finger, then lead them to the fingertips until they extend beyond the fingertips.
Grab the cardboard, then press its print side down on the caulking. Turn the cardboard and hand outline assembly around so that the hand is on the top. Press the hand outline into the cardboard until the caulking wants to escape from under the hand outline. Grab the silicone caulk, then trace an outline from the fingertips to the hand's wrists. Grab the straws one at a time and place them on the caulking. Place one end of the yarn on the wrists and the other yarn end projecting from the fingertips. Add more silicone caulk over the straws, then let the robot hand dry.
After the caulk dries, cut notches in both, caulking and straw, where the joints on a real hand would normally be. Cut the straws sticking out beyond the fingertips so that they're flush with the finger and thumb tips. Cut more yarn, this time using more yarn than what you used for the fingers. Slide these yarn pieces through the straws in each of the fingers and the thumb, then tie them with the original set of yarn you caulked. Make sure you have a good knot, then pull the set back so that the yarn pieces are flush with the finger and thumb tips.
Cut the cardboard backing so that it's flush with the hand, making sure that there's a web pattern between each fingers. Set this assembly aside and let it dry, grab another cardboard and create a second hand, making sure the shape is one that could fit nicely with the original hand cut out. After the caulking dries, add new caulking on the straws but not on the notches that you cut. Place the second hand on top of the first one. Let it dry.
