Sometimes, when we were growing up, someone would leave a container of candy outside, and you helped yourself, but it still sounds kind of risky...unless you have a screen and can sit on the other side of it, and just wave, and tell them to take it themselves? I like the tube better, lol!
No, you don't want to risk them getting out. Your first idea sounds like it would work, though.
You're right, there may not be as many kids this year.
