Here is a mind-distorting experiment! I call it ANTI-GRAVITY SETUP. Even you can do it in your house, it's a 4year old baby experiment but has strong science behind it ;)
Have a look,
EQUIPMENTS NEEDED:
- A DOUBLE CONE. Two cones attached together with their rim.
- A V-Shaped inclined plane!
- CASE 1:
Now, if we keep the cone at the High-end edge of the inclined plane, what would happen? It would roll down under gravity, yeah thats simple science.
- CASE 2:
What would happen if you keep the double cone at the end-down point of the inclined plane? Your answer would be, it would stay there because its the endpoint, right?
But No, it would go up to the top end without any force acting on it!!
