All these years, we have been throwing away toothpaste tubes filled with at least some toothpaste left. If we take into account the amount of toothpaste left in the tubes - no matter how little it was - we must have wasted a lot of money by now. For a budget-conscious person, this trick can prove to be handy.
Take a bobby pin (one the extra-long ones), squeeze and slip the bobby pin on the bottom to secure the tube. Move the bobby pin upwards to ensure there is no waste of toothpaste.
