Marbles in a funnel? Answered

Does anyone remember the museum piece that described angular momentum or some such thing? It looked like a large wooden funnel with marbles that were augered up from below and let loose to roll around and down, spinning up the lower they got? Has anyone made a home version of this? Can something like this be made into a coffee table?

Its just a large funnel. You can easily turn something like that into a glass top table. I see tables like that all the time at various malls. Rather then marbles you drop in coins and watch then spin round.

right, that's exactly what I'm looking for but I can't find them for sale or in blueprints.
