GROAN TUBE



APPARATUS
groan tube
MK


DESCRIPTION
The groan tube contains a party noise-maker on a sliding mass.  Hold the tube vertically and it makes noise as the mass moves through it.  Toss the tube in the air so there is no relative motion between the slider and the tube and the noise stops.
