In this video I show how to make a balloon inflate all by itself using items from my kitchen. I pour white vinegar into a plastic bottle, then load baking soda into a balloon with a paper funnel. When ...

There’s a shocking lack of understanding of the physics underlying this commonplace phenomenon, but researchers are on the ...

The familiar phenomenon has puzzled researchers for centuries, but experiments are finally making sense of its unruly behaviours.

Two microscopic grains collide and produce a tiny spark. This phenomenon may have provided the energy to kick off life on Earth. But if these solid particles have the same composition, what factor ...

Seemingly random charging of identical materials depends on the carbonaceous molecules stuck to their surfaces ...

When particles in volcanic ash cloud rub together, some pick up positive charge and others negative – now physicists have ...
