Fill up a gallon jug of water to make a table lamp
There are a million ways in which it’s possible to harness the power of physics to create a beam of light that shines brighter. For example, if there’s a gallon jug of water and a headlamp at your disposal, it’s possible to use them to make a table lamp.
Wrap the elastic of the headlamp around the jug. The water inside will disperse the light and turn it into a much more effective light source. The photo shows how bright it glows. It also looks pretty cool in addition to being useful.
