These rings are designed with padding to absorb these kinds of moves and keep the wrestlers safe. Don't wrestle on grass, a mat, or similarly padded surface. Only work in wrestling rings for safety. Backyard wrestling rings are available for purchase. Search online for a regulation ring. Some gyms may also have wrestling rings, if you don't want to buy one. Check for any gyms like this near you. Although they look similar, wrestling and boxing rings aren't the same. Boxing rings don't have the same type of padding that wrestling rings do, so you could get hurt working in a boxing ring. While it may not look like it, the tombstone requires both participants to know what they're doing. The other person needs to know where to grab you, how tightly to hold on, and how to roll away when the move is done. It's not something that amateurs can do safely. Always work with a partner who knows how the move is performed and who has the strength to hold you properly. An experienced wrestler can also tell you if you're doing the move wrong. If your partner says at any point for you to stop the move, then stop immediately. Ideally, work with someone who is regularly your wrestling partner. The more experience you have with each other, the safer the move is. If your opponent is heavier than you, this move will be very difficult. You may not be able to support their weight on your shoulder. Even worse, they could shift downward during the move and hit the mat. Avoid accidents by performing the move on someone roughly your size or smaller. If you can legitimately lift several times your bodyweight, then you may attempt the move on someone heavier than you are. But this is the only circumstance that you should attempt the move on someone larger. Never perform any more moves on the person until you're sure they're okay. Stop what you're doing and ask. If they indicate at all that they're hurt, or if they don't answer, stop wrestling immediately and get help. If you're in a competitive match or show and don't want to stop the action, develop a signal system with your partner. For example, they could squeeze your hand after they hit the ground to indicate that they're okay.

summary: Work in a real wrestling ring. Perform this move on an experienced wrestler only. Avoid doing this move on someone larger than you. Confirm that the other person is okay immediately after the move.

This is a great method for pealing an entire head of garlic at once. Remove whatever loose papery skin you can by hand before beginning. Place the bowls together, open side to open side, to form a larger 'sealed' bowl.

summary: Place the entire garlic head inside one stainless steel bowl. Cover the bowl with another identical stainless steel bowl.

Summarize the following:
The air around you is pressing against you and every other object, with a pressure as high as 101 kPa (14.7 pounds per square inch) when you're at sea level. This would normally be enough to crush a can by itself, or even a person! This doesn't happen because the air inside the soda can (or the material inside your body) is pushing outward with equal pressure, and because the air pressure "cancels itself out" by pushing at us from every direction equally. When the water in the can boils, you can see the water start to escape as little droplets in the air, or steam. Some of the air in the can gets pushed out when this happens, to make room for the expanding cloud of water droplets. Despite the can losing some of the air inside it, it doesn't get crushed yet, because the water vapor that took the place of the air is pushing from the inside instead. In general, the more you heat a liquid or a gas, the more it expands. If it is an enclosed container so it can't keep expanding, it exerts more pressure. This is known as Gay-Lussac's Law. When the can is turned upside down in the ice water, the situation changes in two ways. First, the can is no longer open to the air, since water is blocking the opening. Second, the water vapor inside the can rapidly cools down again. The water vapor once again shrinks down to its original volume, the tiny amount of water at the bottom of the can. Suddenly, most of the space inside the can has nothing in it at all not even air! The air that's been pressing from the outside of the can this whole time suddenly has nothing on the other side to resist it, so it crushes the can inward. Space that has nothing in it is called a vacuum. The appearance of a vacuum, or empty space, inside the can has one other effect besides causing the can to be crushed. Watch the can carefully as you lower it into the water, and again as you lift it out. You might notice a small amount of water getting sucked up into the can, then trickling out again. This is because the water pressure is pushing against the opening of the can, but only hard enough to fill a little of the can before the aluminum is crushed.
summary: Learn about air pressure. Figure out what happens when you heat the can of water. Understand how the can gets crushed. Watch the can closely to discover one more effect of the experiment.
