It’s your turn to be a roller coaster engineer!
Your challenge: to make a marble rollercoaster with the biggest loop!
The specs: you can be creative and use any materials you like to design and build your marble roller coaster. The only exceptions are pre-designed marble roller coaster kits, which cannot be used. Like our roller coaster engineer, Joelle Javier, please keep safety in mind!
Parent/guardian supervision is recommended.
