While the table was never upended, there is only maybe a 1/4 cup of rice left in it, the rest having been scattered gleefully during play. Mostly it swept up easily in periodic clean-ups, but I have no doubt we will be finding rice grains for weeks or months to come. Some, clinging to socks and pants, have migrated to the living room and perhaps elsewhere.
So. Totally. Worth it.
I'm not going to make it a regular play station in the house, but boy that's a good thing to have in one's bag of tricks to occupy an active, cranky, bored kid on a rainy afternoon.
