Who wouldve known that you could make hummingbird feeders from ice cream cartons?!
That is until I came across this video by,Robbie and Gary Gardening Easy.
The tray should be about 1 inch deep.

If the tray is any deeper, the birds wont be able to reach the food.

Step Two
Take your other ice cream container and paint the inside of the bowl white.

This is so that the logo will look more prominent and the concrete wont be visible from the outside.
Use a thin coat of paint so it will dry quickly.
The paint doesnt have to be perfect.

Poke holes in the lid so the hummingbirds can get nectar out of the tray.
