Cut several regular sheets of paper in half.
Fold each piece of paper in 1/2, leaving about a half inch showing at the top.
Tape each piece at the top of the fold, leaving the bottom of the fold open for the quarter to slide through.
Tape each folded paper pocket to your wall at different angles. Place the pockets in a way that they can each catch the quarter on the way down.
Test your roller coaster by sliding your quarter down your track starting at the top pocket. Adjust your ramps to fix any mistakes in the speed or direction of your quarter.
Show off your creation by recording your coaster for all to see in the document below. For directions on how to add a picture or video, watch the video here.
