"Let's make a mechanical cardboard hand!"

Materials Required

a piece of cardboard

ten rubber bands

eight drinking straws

some string (about one metre)

scotch tape

liquid glue

scissors

a pen or pencil

a ruler

Instructions

Place your hand on the cardboard and draw around it with the pen up to your wrist. Draw lines with the pen to divide the fingers. Cut around the outside of the hand shape and cut the lines to separate fingers.

Use scotch tape to attach a rubber band to the bottom of each finger, making sure to fix the end of each rubber band (you can leave a small amount loose, fold the rubber band and stick with another piece of tape).

Instructions

Stretch the rubber band slightly and then attach the other end to the top of the finger. The side with the rubber bands is the back of the hand.

Flip the cardboard and stick a little piece of a straw on each phalanx with glue, and a longer piece of straw below each finger, in the metacarpus.

Cut some pieces of string and tie them to the top of each rubber band, then insert them in the straws.

Instructions

Fingers will bend by pulling the strings and then return in a relaxed position with the help of the rubber bands.

Now try to lift a paper cup with a small amount of water and see what happens!
