Mineral Toothpaste
GB and I are learning about rocks and minerals in our Science curriculum. The activity for today was to take two common minerals, calcium carbonate and sodium bicarbonate (basically, tums and baking soda) and make a common, everyday product. By mixing these ingredients with a bit of water you get a toothpaste.
We crushed up the Tums so that we had equal amounts of each ingredient.
Then, poured the baking soda into the bowl with the crushed Tums.
Then we added a little water to make it similar to a paste consistency.
Then it was time to try it out.
GB was not overly fond of the taste, neither was I, it just tasted too salty. But, it did an amazingly good job of getting our teeth nice and white. I guess I now have a back-up if we ever run out of paste….LOL!

I think I will stick with Crest.
But, it looks like a great activity!

Very interesting. I guess the tums would make it better than plain baking soda, but, yeah, I don’t think it would be very good regularly.
