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.
Robot serving ice cream (Fail) At Global Village in Dubai, the ice cream vendor was replaced by IceAlice, a robotic arm capable of serving ice cream. Only when serving this ice cream, the waiter didn't make it. The robot crushes the cup, the ice cream falls into the void, and the arm clamp breaks.
The ladder he wanted to kill itself On the roof of a house, a ladder moves by its own weight in such a way, reminiscent of a four-legged animal. The ladder reaches the edge of the roof and then drops into the void.

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.

A kid robs the fridge A mother finds the refrigerator open and various candies and chocolates on the floor. Following the tracks, finds her toddler sleeping peacefully on the chocolate covered sofa.
Rail welding Although in the past the rails had to have a gap between them to cope with temperature expansion/contraction, this technique is no longer applied to high-speed trains. The rails are welded together for several kilometers, and then heated to a high temperature to fully expand. Rail fasteners use very high clamping force, and so the contraction is much less. A second technique is the expansion joint, which may be different: it is no longer a mere gap, but a smooth joint where the two rails are side by side and when they grow or shrink in length they can slide next to each other.
The blossom of an acorn in 196 days A timelapse that shows us how the flower of an oak grows, which is initially placed in a jar with water only, and then in a flowerpot.
