Your kid hasn't started studying physics yet, but he's happy to skim the catapults, trying to build an improvised parachute and put a man out of Lego on it, and the fascination equals various objects? Then experiments from Tom Tita's Tests. An amazing mechanic. Today is the force of gravity: home experiences For children with a warehouse knife and forks, it's like a miracle, but it just shows the laws of physics.

Self-equipping knife

Almost any body that is sufficiently uneven (not vertical) to the ground and unsupported is seeking to fall as a result of the force of gravity. You'll make it easy if you start bowling a vertically worthy bottle or a bank.

Attention: Adult experience

The force with which the body operates on the foot is called body weight, and the point where the force is attached is the centre of gravity of the body. For the object to be stable, it must have a broad base and the centre of gravity is as low as possible. For example, a board lying on a plate is much more stable than a standing torch.

However, an uneven object can be made to stand steady without additional support. Learn to learn how to do it.

What will be required:

• warehouse knife
• a hook worm at the end of the hand
• salt
• tea spoon

Experience. Open the warehouse knife, but not the end, as shown in the drawing. Make sure it doesn't fold up and squeeze in small presses. If you can't record a knife in a semi-disclosure state, his blade can be a little blade between him and the puzzle in a matchbox.

Now put a knife on the edge of the table and put a worm on it, as shown in the drawing. If necessary, if the design is to be more easily assembled, ask adults to adjust the bending of the worn with a massage.

Result. After a few hesitations, the resulting design from the knife and the worn will be balanced and stable enough. Without a worm, a knife on the edge of the table could not resist a second, and now it can even be pumped!
