Lifehack 1: To keep glasses or a mirror from fogging up, just evenly apply some liquid soap to the surface, then remove the excess and polish with a paper towel. They won't fog up for a long time!
Lifehack 2: To pump water out of any container using a bottle, you need to make holes in the cap and bottom of the bottle, thread silicone tubes through the holes, and seal. Lower one tube into the container, clamp the other shut, then squeeze the bottle. As soon as water begins to fill the bottle, you can release the second tube, through which the water will pour out.
Lifehack 3: A simple electromagnet can help in the search for metal. Wind some copper wire around a nail, clean the contacts, and connect to a battery pack using crocodile clips. The magnet attracts metal objects!
Lifehack 1: When hot steam touches a cool mirror, it fogs up due to the condensation of water vapor: a lot of tiny water droplets form on the surface of the glass. When soap is applied to the surface, the surfactants that make up the soap remain in a thin film and prevent the formation of droplets.
Lifehack 2: In squeezing the bottle, you push air out of it. Due to elastic force, the bottle partially expands, and the pressure in the bottle decreases. Water begins to force its way into the bottle, filling it, and then pours out through the second tube.
Lifehack 3: An electromagnet consists of a coil and a ferromagnetic core. A magnetic field arises when electric current passes through the wire, and the core amplifies it, also acquiring magnetic properties.
