Magnaprobe
(3D compass): How it works

A 3D compass always aligns itself to the magnetic field
it is in, such as the Earth's magnetic field. Watch how the needle
maintains its position even though the handle is turned.

Marshmallow
Man

The air pockets in jetpuffed marshmallows will
expand in a vacuum. This makes the marshmallow man get bigger as
the pressure inside the bell jar gets lower.

Newton's
Cradle, nine balls

In all cases, the momentum of the excited ball(s)
will be transferred down the line on balls, exciting an equal amount
of balls at the end. For example, one ball given an initial momentum
will cause one ball at the opposite end to have the same momentum
after collision.

Newton's
Cradle, only two balls

In this case, the momentum of the excited ball
is transferred to the other ball of equal mass. The velocity of
the second ball after collision is the same as the first's before
the collision due to the conservation of momentum.

Newton's
Cradle, big and small ball

In this case, the larger massed ball has a low
velocity. When the momentum is transferred to a lower mass ball,
the velocity must go up in order to maintain the conservation of
momentum.

Newton's
Cradle, all balls

In this case, the momentum of the large excited
ball is transferred to balls at the end. The momentum is split primarily
between the end three balls, the two inner ones each having a velocity
equal to 1/2 of the previous. This gives rise to the doubling in
distance seen between the end balls.
