Found this on Amazon for a steal! We purchased it for making bathbombs for my sons school project. Truly great product! We use a small coffee grinder to break up the clumps. Will purchase again.

I purchased this for the purpose of making bath bombs.

This definitely did the job! the reactions of the powders in my bath bombs kept my bath fizzing for 45-60 minutes (and probably beyond that).

There are some large clumps of citric acid in the bag - but they are easily broken up with some easy massaging of the clumps.

For the price of this product, a few lumps aren't a huge deal.

The powder is quite fine, and the bag is huge and should last for quite a long time. I'll definitely purchase this again for future DIY!
