Littleredd1333 - Circles & Triangles

If you dropped a water balloon on a bed of nails, you’d expect it to burst spectacularly. And you’d be right – some of the time. Under the right conditions, though, you’d see what a high-speed camera caught in the animation above: a pancake-shaped bounce with nary a leak. Physically, this is a scaled-up version of what happens to a water droplet when it hits a superhydrophobic surface. 

Water repellent superhydrophobic surfaces are covered in microscale roughness, much like a bed of tiny nails. When the balloon (or droplet) hits, it deforms into the gaps between posts. In the case of the water balloon, its rubbery exterior pulls back against that deformation. (For the droplet, the same effect is provided by surface tension.) That tension pulls the deformed parts of the balloon back up, causing the whole balloon to rebound off the nails in a pancake-like shape. For more, check out this video on the student balloon project or the original water droplet research. (Image credits: T. Hecksher et al., Y.

It’s like being home sick for a place that doesn’t exist.

Let your smile be sincere and let your heart be warm, there is not enough time in the world. Bitterness is only going to bring you down, slower your pace, and hurt your soul, where it is possible it should be avoided. Wake up grateful and be proud of who you are, where you have been and where you are going to go. Leave nothing but happiness is your heart, as well as others. See where joy can carry you.

be grateful, be proud by Amy Kennedy
