The flat red springboards can launch you in the air if you time your jump. Jump just as your character is in the middle of the board, past the white line. If done correctly, your character will be launched very high into the sky. You can earn bonus points while in the air. After a flat springboard catapult, your character cannot jump out of that trajectory. Tapping will give you bonus points while he is flying. Tapping repeatedly will award you even more points.
