Potassium Iodide, 99.9% Purity, Powder/Crystals, 100g Lab Grade, for Elephant Toothpaste, Potassium Iodide Powder for Laboratory Teaching

We purchased this to make elephant toothpaste. It worked perfectly. It was so easy to make and the entire neighborhood learned a little science lesson! It was so fun. If you have children, I definitely recommend that you look this up and try it. It was so cool!

We use this during our science class, for different types of experiments. This is so fun to use on the elephant toothpaste experiment, when doing a volcano or just for fun projects.

Worked great for the elephant toothpaste experiment! You have to, of course dissolve it in water first. If you do choose to buy it for this experiment, just remember the chemical reaction is quicker than when you use peroxide and yeast. This means instead of the foam being cold to touch, it produces energy as heat and will be hot to touch

It was bought as a science experiment and worked well

Purchased for an elephant toothpaste experiment in school. Worked perfectly and I have plenty left for future experiments.

Worked well for my use as a teacher. There were no issues with this product except for the box it came in was covered in powder.

met all expectations

Shipped fast and everything seems ok
