YouTube The action lab it always brings us interesting and exciting experiments and it’s no secret that we are big fans. From his videos where he does water dance on a flat surface of those who do laser microscope just a drop of waterYouTuber always mixes with physics and engineering to make us happy and entertained.

In this last experiment, he shows us how to eliminate light waves. To do this, he must create an environment in which there is air, water and then air again.

He does this by using a soap bubble. As it casts white light on the soap bubble, we can see that the top is completely black, which means it does not reflect any light. In other words, the light waves are canceled.
