  HOLE IN YOUR HAND

Materials:
Sheet of stiff paper 12 x 8 inches
Tape

Make a tube by rolling up the sheet of stiff paper. Tape the edges so the tube
holds together.
Hold the tube up to your right eye. Hold your left hand up beside the tube.
Stare hard down the tube, keeping your left eye open. Do you see a hole in your hand?
What happens? One eye is looking down the tube and the other is looking at your hand. The
two views mix together so you see a hand with a hole in it.

 

MUSCLE PULL  

Materials: Pair scouts sitting across from one another with a table
between them.
Have Scout #1 press his hands tightly together. Have Scout #2 try
to pull them apart by gripping each wrist and pulling them to the
side.
Scout #2 will find it very difficult to pull Scout #1' s hands apart in this position because the
muscles being used for pulling are not used very often.
Try the same test again, but this time Scout #2 crosses his hands over and pushes Scout #1' s
hands apart. It is easier to move Scout #1' s hands apart because different muscles are being used.
These pushing muscles are stronger because they are used more frequently.
