Review on Innovating Science Instant Powder Chemiluminescence by Will Schimmel

We haven't used the product so I can't check the quality but I'd like to point out that the description is very misleading. This is NOT a 4 ounce product or anything close to it. That's about 20 grams or 4-5 teaspoons of powder. This is enough for 4-5 experiments, so it may be enough for your needs. When it arrived I was surprised that the bottle was only 1/3 full and not sealed. I thought it might have been opened before but after reading the instructions somewhere it said it was 20 grams and that's what I got.
