Bed of Nails Demonstrations
Bed of Nails & Person Standing
One person lies on a bed of nails, while another stands atop a bed of
nails
resting on the others chest. This shows that with fairly even
distribution
there are enough nails that no one of them presses with enough force to
cause pain.
Bed of Nails & Block Broken
A concrete block is placed on a small bed of nails, nail points down,
which in turn is placed on the chest of someone lying on a large bed of
nails. The block is then broken with a sledge hammer. The energy of the
hammer goes mostly to the inelastic collision with the block, the
momentum
through to the Earth. It's the little bits of concrete you have to
watch
out for. Wear a face mask and a cup! I prefer to use a three
section
block and have the middle section broken. That way a lot of the small
pieces
of concrete are stopped by the two end sections.
