Safe­ty pre­cau­tions
Avoid swal­low­ing the tooth­paste
Warn­ing! Only un­der adults su­per­vi­sion.

Reagents and equip­ment:
* 50 g of bak­ing soda;
* 20 ml of glyc­erin;
* 15 ml 3% hy­dro­gen per­ox­ide so­lu­tion;
* 15 ml of wa­ter;
* 1 drop of mint fla­vor­ing;
* mix­ing bowl;
* con­tain­er for the tooth­paste.

Step-by-step in­struc­tions
Stir the bak­ing soda, glyc­erin, hy­dro­gen per­ox­ide, wa­ter and fla­vor­ing un­til a thick paste forms. Pour the mix­ture into the con­tain­er and keep in a cool dark place.

Pro­cess­es de­scrip­tion
Par­ti­cles of bak­ing soda act as an abra­sive and re­move plaque, and the glyc­erin makes the mix­ture paste-like. Hy­dro­gen per­ox­ide kills bac­te­ria and elim­i­nates bad breath. The mint fla­vor­ing gives the paste a pleas­ant taste.
