Testing

The cup is made of a very durable plastic.

It has been impact tested by striking it with a puck at the equivalent*

momentum of a 100 mph slap shot. There was no damage.

The momentum was doubled to 200 mph. There was no damage.

Play Safe!!!!!   (see video under MEDIA)

* Momentum is =  MASS  X  VELOCITY

Since there is no reliable method to accurately propel a puck at 100/200mph

we used a gravity drop to impact test. The formula a=9.8m/ss was used to

determine the velocity from a given height. The MASS of the striker was increased

appropriately for equivalence to 100/200mph slap shot.
