rainbow shaker
This one can either be an activity or just a party favour to take home for a fun rainbow party. Collect some plastic bottles (the smaller the better) and some rainbow coloured shakers - beads, shells, rocks, rice, buttons, smarties, whatever you can think of. You can let the kids fill up the bottles at the party, or do it yourself. Add some coloured streamers around the lid and you have a fun rainbow shaker they will love!
