The marbles of the world are moving too fast and I have a solution. It’s about as simple as taking your first step. Here’s my explanation
1.
Slowly release the six inch string (the string is taped to the marble), letting it drop.
2.
Once in funnel, it will spin around before dropping again.
3.
Once it is in the tissue box, it will hit the flap (which is cut from the box), and continue rolling.
4.
Now, it will roll down the PVC piping, and fly up into the air, thus, coming back down and completing my course.
MATERIALS:
1.
6 inch string, and one piece of tape.
1.
5mm marble
1. 9x5 tissue box
1. PVC pipe, cut in half
1. Funnel, plastic

My solution is the best because when the marble is moving, it can not go wrong, because every item in the solution will be connected together, and also the string will create drag, when going with marble.
