These are some experiments to provoke thinking about physics and do not do
these at home
1.put a metal between two electromagnets
2.drop two masses of different weights inside two vacuumed tubes
3.try to go higher by running at a vertical wall
4.put two ropes alligned so that they appear undeminished to a point opposite to
xeno's paradox
5.make an indefinite number of aeroplanes fly very near to each other and
measure time dilation
6.get a hollow sphere and make two carts move on the inner wall of the sphere
7.get a long laser and while turned on make the back mirror pushed to the front of
the laser at high speeds
8.get two laser of some two colors and put them at a distance from each other and
while they are opposite to each turn them on
9.make cars speed up and explode them with explosives
10.get a pot filled with water and run with the pot without spilling water
11.switch a switch on and off(preferably at the speed of light)
12.scream in water in a swimming pool
13.put pressure on clocks while they are underneath water at different levels
14.make huge clocks that go very slow and measure the time dilation
15.get pointers of different metals spinning in a circle at various speeds and of
various radii and measure when the pointers are alligned
16.measure inertia stopping effect
17. get two electromagnet and as they are on spin the two electromagnets around
each other in an orbit
18.run through gates that turn off as you pass them
19.make an electronic watch send signals inside of itself till the last signal says the
time
20.scream onto a mountain and run away at the speed of sound
21.do friction on different metals and see how much heat comes out
22.heat a mass then cool it down and measure fracture overload to know bonding
energy amount
23.shoot electromagnetic waves from earth to satellites
24.escalate the tone of your voice and then increase the raging fast and measure
the temperature inside a thermos
