Vials that hold fresh cut flowers that florists use.. recycle them to make hummingbird feeders..
I think you could probably paint them red and then even hold them in your hand, children would love to watch the hummers eat from their hands..
I haven't used them yet, I'm waiting for the hummers to show up in more numbers, right now we only have one here. You could probably put them in every flower pot you have or baskets, etc.. just stick them into the soil.
