I Built a Roller Coaster In My Lab

Summary by Krater

Mark Rober builds a custom indoor snow roller coaster and tire swing for a boy named Ethan who recovered from a rare neurological condition, testing various rocket and turbine configurations with cartoon-inspired pranks.

Answers: How do you build a Phineas and Ferb indoor snow roller coaster in real life?

• indoor roller coaster build
• Phineas and Ferb birthday party
• rocket-powered tire swing
• cartoon physics testing in real life
• snow cone machine and snow maker

What it concludes

• Rocket-powered tire swings rely heavily on the creative boundaries of cartoon physics with peak forces 35 times what a human can endure.
• A dual chain configuration provides much more stability for a rocket-powered swing.
• Swapping chains for solid rods allowed the rocket forces to rip the half-ton steel swing structure out from the stakes anchoring it into the ground.
• Swapping rockets for a pair of 24-volt electric turbines provides smoke-free thrust and allows precise tuning to the natural frequency of the swing.
• An 8-week virtual space-themed summer camp helps kids fight summer brain drain with weekly videos and mega experiments.
