So, I've come up with a cheap and easy way to do this. I take a 5 Gallon bucket and cut out a piece of foam padding to match the circumference of the pail This 'floating raft' stays moist but they bees can still land on it, drink and fly away with no danger of drowning.
Plus, I can add mineral salt to the water and they can get their necessary minerals as well. The foam also keeps it from evaporating too quickly. I have yet to fill it or top it off yet.
