3 चमत्कारी प्रयोग || Science Experiments About this video = In today's video, We will be doing 3 Easy And Amazing Science Experiments For Kids Which you can Try At Your Home...... Reason Behind :- 1st Experiment - It is based on the principle of thermochromism, a process of change in colour with heating. Thermal printing essentially works by creating impressions using print-heads over a special kind of paper roll (found in ATMs, vending machines) coated with organic dyes, waxes. 2nd Experiment - The sound it produced when travelling air molecules hit the tube's inner ridges and vibrate against them. As you whirl the tube faster and faster, the whirling end's air pressure is lowered, and air moves faster through the tube to fill this low-pressure area. And when we cover one end if pipe with our finger, the sound is not produced. 3rd Experiment - The real force in action here is called centripetal force, which means center-seeking. This is a force that is always directed toward the center of circular movement and is actually responsible for taking and moving marble in a circle. Inside the glass, it's the wall of the glass that causes this to happen
