I don't know of a specific wholesale source, but I think I know which
top you mean:

It's made by Schylling (www.schylling.com).  Here's a link to their page
with that top:

=4034&Category_Code=CP&Product_Count=4
<http://www.schylling.com/Merchant2/merchant.mvc?Screen=PROD&Product_Cod
e=4034&Category_Code=CP&Product_Count=4>

I don't know of a specific wholesale source, but if you have a gift
shop, I bet the person who orders products for it could order some for
you at wholesale prices.  There's probably information on Schylling's
website.

Good luck!

You know those spinning tops (old toy) that have the red, yellow and
blue disks inside that spin as the top spins?   As the disks spin, the
colors change.  Anybody remember these or sell them in their store?

1.   I need an elementary level explanation for why the colors change as
they do.  
2.   Anyone have a wholesale source for these tops?

Thanks,
Kristie, SD Discovery Center
