1)NEVER THROW AWAY YOUR OLD PEN EYELINERS.You know why??Because you can simply take out the pen part and swap the two sides around,and it will be working perfectly just like brand new.(Not all pen eyeliners are like this).
2)Want whiter teeth?Mix baking soda with toothpaste and brush your teeth with it once a week.Well you could go buy a baking soda toothpaste,but you know there are a lot of chemicls inside.However this will not,depending on your toothpaste.
3)Really annoyed when you wake up in the morning and see a little enemy on your face?Easy.Just take a bobbi pin and press against your skin until it comes out.(Never use your nail this can damage your skin very badly and leave scars).
