In the "Cardboard Roller Coaster" event, clubs constructed a marble roller coaster out of recycled cardboard materials while following a series of design constraints. Photo: Douglas Levere

Time to test it out. Photo: Douglas Levere

The marble has to make in safely through the coaster's turns and gaps. Photo: Douglas Levere
