Potassium Iodide 100g, Fast-Acting Catalyst, Elephant Toothpaste

Bought for science and it did the job

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!

Good quality

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.

Ordered and received in 2 days. Exactly what it was. potassium iodide. Thank you

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

The bottle claims 99.9% purity, but when dissolving in water, a lot of solid remains, and KI is very soluble, so this makes me doubt the purity. KI has a solubility of 1.4g per 1 mL, and I used more water than this ratio, with heat, and there is still some undissolved material present.

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.
