You know it as well as I, a tube of toothpaste is never really empty.
Considering the price of a tube of toothpaste and the amount you have to buy each year, it's worth finishing them all the way, isn't it?
Here's a simple little trick to really empty it completely.
1. Cut the end of the tube with scissors.
2. Insert your toothbrush to collect the precious product. There you go!
