Bionic Hand

First of all, cut a 40 cm long corrugated cardboard arm with a hand on the end. The grooves of the cardboard must be longitudinal. The elbow of the arm should be slightly wider. Then cut two more pieces of cardboard. One must be 4 x 32 cm and the other 4 x 35 cm.

Now you have to decide whether to use your right hand or your left hand. If you are going to use it with your right hand, place the cardboard on the table with the palm facing down and secure the handle by gluing the short one of the cut strips.

Then turn the sleeve and glue the longer strip to the wider part of the sleeve close to the elbow. This will be the part you keep.

Now fold the fingers three places with the help of a ruler. These will be the joints of the mechanical hand. Now cut eight pieces of 1 cm length from a plastic pipette.

Cut thin strips of a solid tape and glue them between the knuckles. Then cut four more 3 cm pipette pieces and glue them to the palm of your fingers.
