Young Noah wants to take his squash game to the next level, so Dr. Heather sends guest pro Maria to demonstrate hitting the ball into the nick, the area in a corner of the court where the wall meets the floor. Noah and host Nykeem learn how the ball is deformed when it hits the wall and the floor in quick succession, reducing its bounce and making it impossible to hit. Squash began in England in prison yards, and in 1830 a school called Harrow developed the modern game. Squash is a very active game and players burn a lot of calories.
