My son signed up for the science fair and said he would be testing a laser with convex vs concave lenses to see which would pop a balloon better.
Can someone point me to a laser that will definitely pop a dark balloon, and a couple lenses that he can experiment with please. I see alot of the lasers are focus-able, but I think he wants external lenses.
Any help will be greatly appreciated
