Tristan tests if the lightproof milk bottles really are lightproof
Tristan Pang is just 12 years old, but he is pretty good at science and maths. So good he started Maths at university this year, 6 years earlier that most of us!
Tristan wanted to know if the lightproof milk bottles were really lightproof, so he managed to get some time on the HeNe laser at the University of Auckland and tested if visible light passed through the bottle by placing the bottle between the laser and a light sensor. He found that the light did not pass through the lightproof bottle, but did pass through a normal milk bottle.
