A simple faucet, using physics The construction of a simple faucet in the countryside using air pressure in a bottle. Water flows out of the yellow straw if the pressure in the bottle is greater than atmospheric pressure. By moving the blue straw up, we reduce the pressure on the end of it and air leaks through it. Because there is a leak, the air gap is reduced under the lid and the water flows out. By moving the blue straw down, we increase the pressure at its lower end due to the water column and the water stops flowing.
Have you seen a large beach worm?; The beach worms are far away, marine invertebrates commonly found in sandy coastal areas. They can grow up to 3 meters in length and are known for being impressive, their iridescent colors. Beach worms burrow into the sand and create vertical U-shaped tunnels, with one end extending to the surface for food. They play a key role in maintaining beach ecosystems by aerating the sand and recycling nutrients.

The fountain chain The chain-fountain phenomenon, also known as Newton's beads or the Mold effect, is a natural phenomenon observed with a chain placed inside a jar, when one end of the chain is pulled from the jar and allowed to fall under the influence of gravity. This process creates a self-sustaining chain flow that rises above the edge and descends to the ground below it, as if drawn from the jar by an invisible siphon.
Because in some areas of the Earth it does not get dark In some areas of the Earth during the summer, the Sun remains visible for over 24 hours or even months without getting dark. This phenomenon is called "Midnight sun" and is observed at latitudes above the Arctic Circle and below the Antarctic Circle. The phenomenon is due to the inclination of the vertical axis of the Earth by 23 ° 26΄ in relation to its plane of rotation around the Sun.. Its duration depends on the latitude, from which we observe it. The closer the observer is to the north or south pole, the longer it lasts. For example, the sun shines continuously for 6 months on the poles, while in the northern tip of Finland it is limited to 73 days. The opposite phenomenon, where the night lasts for more than 24 hours during the winter, it is called "Polar Night".
Rotating table with robotic claws The robot and animatronics film designer, Mark Setrakian, made a robotic tip with nails, that can spin a disc with precision and constant speed.
Cutting solid steel with a thermal lance The thermal lance or oxygen combustion rod, is a tool that uses the exothermic reaction of steel and compressed oxygen to cut metals or reinforced concrete.. The end of the steel tube is first heated to a high temperature and then oxygen is compressed in the tube. This causes an exothermic reaction in which the end of the tube melts (> 4000 °C) and cuts other materials with oxygen.
