I posted this on another site as well. It is a simple kitchen table project and cost under $15.
glass beads $3 (at Big Lots or a Dollar Store)
aquarium sealant $8
cap from a jar of spices.
Start out by covering the cereal bowel in olive oil, this is to help prevent sticking to the bowel. There are other variations, plastic wrap, wax paper and such. Most people have one of the items in their kitchen. I chose olive oil cause it is natural and figure a bath in hot water after curing would take away any residue oil.
Start out by dabbing the sealant on one side of a glass bead, leave a spot for the door (spice jar lid, also oiled up).
Once you have the first row squeeze out a bead all the way around teh top of the glass beads.
rather rinse repeat
I goofed up and did not put the spice jar lid in....
