Saving drowning bees
It's hot here in the UK just now. Americans will laugh at us, but it made 37C where I am yesterday and we're not prepared for it. So we got our pool out.
I've already rescued two bumble bees who were really struggling and scooped out a few more who didn't make it.
Does anyone have good ideas for things we can float in the pool for bees to land on and drink? I've seen wine corks used before but they look like they'd just roll if a bee landed on them. Any better ideas out there?
