Solution A Mushroom
You are trapped in a room with no windows and a door that's locked the only furniture is a piano, a calender and a spring mattress. How do you eat, drink and get out!!!??
I can travel at nearly 100 miles per hour, but never leave the room. You can cover me up, but that doesn’t slow me down. You will not know if I come only once or again and again and again. What am I?
