HOW

• The rockets has 3 levels: 0 m, 2 m and 4 m.
• You can exit the upper levels in emergency mode – down slides that have different shapes. Which one do you move fastest on?
• One of the slide shapes is a slice of a curve, called a cycloid. You can find out more about this at the Brachistochrone Curve device adjacent to the Supercool Playground.
