Make an Anti-Gravity Machine


What You Need:


At first glance the taped funnels appear to defy the laws of gravity. However, in reality, the centre of gravity (the point at which the effect of gravity on an object is concentrated most) on the anti-gravity machine moves downwards as the joined funnels move along the inclined rulers. The centre of gravity on our machine is the middle section where the tape connects the two funnels.
