Sensory Table Ideas

There's been a recent discussion about the use of food in sensory tables. I do use food, I've used the same rice & beans for the last three years, so it's not like I am consistently wasting food. Considering how difficult it is to get rice these days I would not buy new rice to use. I actually inherited my rice from a head start program when their policy against food items in the sensory table went into place. We do jell-o and pudding finger painting as sensory activities as well--of course those are done on individual trays! I would reconsider my view if I was in a situation where I did have children who were not getting enough to eat, but so far that hasn't been the case (and it is unlikely to be the case--since those parents don't often pay for private preschool). I figure if I get really desperate I can count that as my food storage. ;-) Not sure how the colored rice would work, but the beans should be fine! I've also used cooked spaghetti, both cooked and uncooked popcorn (under supervision--since it is now considered a choking hazard), and corn meal. My favorite this year was the good, old fashioned sand. I actually took a trip to the sand dunes & filled a bucket full of real sand-dune sand (it's legal--I did check!!!), and the kids have loved it. I've suggested rotating other materials several times, and have been out voted. Our sand/water table is outside, inside I use a large tupperware box (the under-bed storage type). I also had beach sand that we used inside with our hermit crabs, that was a favorite. We finished off this year with colored ice cubes, to conclude our year-long investigation on color mixing. The kids enjoyed that--more so the melting the ice cubes than actually mixing the colors. Thinking back, I kind of wish we'd had the light table out for that project--could have been interesting! There's a great list at preschooleducation.com, I hope this link works! http://www.preschooleducation.com/ebook/sand.pdf Curious for those that have water tables--do you have any trouble with licensing? For our water area outside I have a large washtub filled with water--I dump it out after every use. But since I think it is deeper than 24" I am wondering if licensing will allow that next year. I have loved it so much better than the plastic tubs I was using, I hate to switch back! I'm also wondering about rain barrels--how have those worked for those who have them?
