Are you looking for something fun to do at home that has a little bit of science behind it?
Make a wiggle robot to draw for you!
Be sure to check out GMSA @9 on Wednesdays when KSAT Meteorologist Sarah Spivey does the demonstrations and explains the science behind it. To view, click on the video player above. Check out our Science with Sarah webpage for more fun science experiments!
HERE’S WHAT YOU’LL NEED
- A plastic cup
- 3 washable markers
- A permanent marker for decorating
- Electrical tape
- Scissors
- 2 AAA batteries
- AAA battery holder (LIKE THESE)
- 1.5V - 3V DC Motor (LIKE THESE)
- Clothes pin
- Piece of paper
DO THE EXPERIMENT
- STEP 1: Draw a silly face design on the cup
- STEP 2: Tape 3 markers to the bottom of the cup and make sure it stands up straight
- STEP 3: Test out your motor by matching the battery pack leads to the motor. Tape the leads to the motor and make sure there is good contact
- STEP 4: Tape the battery pack to the back of the wiggle bot and the motor on top of the cup. Make sure the motor is hanging off of the cup with enough room for a clothes pin to spin around
- STEP 5: Clamp a clothes pin onto the rotating part of the motor and set the wiggle bot onto a piece of paper. It may take some adjusting here and there, but you should get the robot to wiggle and draw on the paper underneath...awesome!
