Marble Drop With Triple Vortex

I guess the marble drop is becoming an annual event- Here is the one we made last year.

This year the monkeys had the genius idea of using these cones, which I have no idea where they got- 

I suppose it would be easy to make them using paper- They loved the anticipation of waiting for the marble to fall and thus the game engaged them for longer. 

We made this marble drop using the cones, recycled egg cartons, gift wrapping cardboard tubes and lots of tape. Egg cartons were numbers at the bottom and points assigned to each cup- 

We have a large mirror which they used- last year they used a window door- makes the tape removal less damaging- 

Do your monkeys love to make marble drops?
