Quadrilla Marble Run Funnel

There are two versions: vortex and bowl. When you drop many marbles into a bowl they may block each-other and get stuck in the bowl. Vortex has the least chances of self-blocking marbles, while maintaining a wide opening at the top. Bowl may be better when you catch marbles the are falling from a slide because they have smaller chance to bounce out of that funnel.

Have fun :)
