On March 5th, 4th Grade  will be having an invention convention. I will be inventing a hat that will also be a pillow, I call it the  P-Hat ( pronounced Fat) The P-Hat is a baseball cap with an air bladder inside, there will also be a piece of Velcro on it to attach a stuffed animal to it, and a small plastic tube which will hold a toothbrush. When you are very tired but you aren’t at your house you can use the P-Hat to take a nap while either on a car trip or commuting.
