It thus takes the shape of a pancake (again) but this time, the drop is in midair. This phenomenon is different to a drop falling on other surfaces as in this case, the drop crashes on the surface leaving only a small quantity of the water to bounce up. Physicists have also found out that the actual speed of a drop influences its deformation but not the time taken for it to get in contact with the surface. Article: Do you know what happens when a drop of water hits a non-absorbent surface? Yeah you’re right (if you don’t have the answer, please re-read the title of this column), the drop echo upwards. A French scientific team from the Collēge de France have studied the scene sparingly with a concave lens that took 40000 images per second. Here are the results: At first, when it hits the surface, the drop flattens. Then, it signal up due to the movement energy it had when falling down. The drop will continue going upwards eventually taking the shape of a needle. Afterwards, the drop falls upon itself, into itself. It thus takes the shape of a pancake (again) but this time, the drop is in midair. This phenomenon is different to a drop falling on other surfaces as in this case, the drop crashes on the surface leaving only a small quantity of the water to trip up. Physicists have also found out that the realized speed of a drop influences its deformation but not the time taken for it to get in contact with the surface. This veritably depends upon the mass of the drop. Anyway why is all this stuff important anyway? Scientists swear by that this find may be of interest to the industry. There’s a small illustration: Imagine not seeing droplets of rain on your car’s windscreen when it is in fact raining cats and dogs outside. Cool, isn’t it? Well this may well be possible with these new data obtained by the scientists from the Collēge de France. How though? Easy enough! The period of contact of the raindrops with the windscreen is so minimal that the driver does not even see them! Water drops bounce like springs, would you ever have thought of this? No, I’m not sure you would.

A History of Elasticity Summary:Man has, since the early times, found out how useful elastic materials are. And today's man has improved on this idea and constantly finds ways to make more elastic materials to suit his everyday needs. Elasticity refers to the property of an object to deform when load is applied to it, and to return to its natural form when the load is relieved. They are also useful in cases where you need watertight equipment. Elastic materials are also handy in creating cushioning materials: tires, so… 3. What if a Living Planet Got Hungry?
