Cut up the bottom half of the egg carton into individual cups. Trim off the edges of each of the cups. Try to make the cups as even as possible around the top edge.
In one of the cups, put a handful of dried beans. This will make the pleasant sound when the shakers are moved.
Put two of the cups together and tape together with paper tape, to make a hollow shaker with the beans inside. Use paper tape, so that it can be painted.
To make the seam more secure, add a layer of tissue paper with glue. Stick pieces of the tissue paper over join of the cups, all the way around, using the glue. This will smooth out the taped seam and will make the seam more secure so that it doesn't open up and spill the beans!
Paint each shaker with a different bright color. Make your little shakers look happy by painting eyes and a smiling mouth.
