6. Toothpaste to get rid of the itch caused by insect bites.
Toothpaste can be used to treat skin irritations caused by bug bites. In emergency situations, it can also be used to treat athlete’s foot and even blisters. Toothpaste can stop itching and reduce swelling when applied topically. For blisters, apply it over the blister before going to bed. It will dry up the blister while you sleep. It also cools and soothes minor burns if applied immediately after they happen.
Caution: Use toothpaste to treat only minor burns. For severe burns using toothpaste can do more harm than good.
7. T-shirt to filter water
There are many ways to filter water if you get stuck in an emergency situation and have access to water that is undrinkable. Fill one container with the murky water. Cut a strip of clean cloth from your t-shirt and dip one end of the cloth in the murky water and put the other end into an empty container where you want to gather the filtered water. Remember to keep the container with the dirty water at a higher level than the other container. After some time you will see clear water dripping into the empty container.
Caution: After you get the clear water, remember to boil it before drinking.
8. Fork as a weapon
Most of us have access to a fork at home and also while we travel. The pointed edges of a fork can be used to fight back against a wild animal that might be trying to attack you or to scare off some stranger trying to get too close and harm you.
