Plastic Cup Lids
Did you know, the ridges on the inside of the plastic lids are there to turn the lid into a coaster? Yes, it is, simply take the lid off, flip it, and slot the cup into the inner section. Why not try this thing next time you get an iced coffee from your favorite coffee shop. Did I just blow your mind with a plastic cup?
Detachable Car Headrests
One time I accidentally removed the headrest while playing inside my dad’s car. Don’t worry, you didn’t break anything. The headrest was designed to be pulled out of the seat in case of an emergency. The metal underneath it can be used to break a window. Be careful and just use it in an emergency.
