Does anyone have any good ideas for a soap dispenser (or a brand of refillable store-brand pumps) that are mostly kid-prooof? I just moved into a new art room with brand-new sinks and I'd like to keep things as nice as possible. I would love a pump that also gives only a dime sized amount of soap for each whole pump. I've only had a room my first year teaching and then I was using these Dial-brand soaps because I got a bunch of them very cheap from BJ's. They were pretty awful if I remember correctly - the pumps broke on them before the soap was ever out. And that was with me doing all the soap pumping for the 1st and K's. I'd like to keep it fairly cheap but if it's a durable reusable pump, I'd be willing to pay up to $20.
