How to make a “bionic” cardboard arm

Untitled

If you have always wanted to have a robotic arm like the ones you see in sci-fi fiction, this is your chance! YouTube channel crazyPT made a nice tutorial on how to make your own cardboard arm. Of course you can always use the kids as an excuse to make this without looking ridiculous.

To do this project at home, you will need:
– A piece of large cardboard
– Clear pen barrels or clear straws
– Elastic bands
– String
– Hot glue

Don’t forget to cut the elastic band slightly smaller than the size of the fingers, and to calculate the string size considering the middle of your hand. Get to work and have fun!
