Frankie turns 2 years old the 28th. To celebrate the upcoming energetic 2s, I'll be spending the day with her in daycare with all her little friends - helping, reading - and doing science experiments. If you Google "slime recipes", there is NO shortage of results. The various formulations provide gooey products with consistency ranging from slime to silly putty. I stumbled on one that's closer to the silly putty side of the continuum and isn't too messy. After all, there's a reason there's no frosting allowed on desserts in the Penguin Room.
Here's my version of Slime for Toddlers: A solution of Elmers White School Glue is mixed 1:1 (v/v) with water. This makes a soupy opaque white solution which can be colored with food dyes (I skipped the dyes at this stage). A second solution is mixed from 20 Mule Team Borax (10 grams) and warm water (270 grams). A ziploc baggie is charged with the glue solution (50 mL) followed by the Borax solution (20 mL) using a children's 5 mL medicine dropper. The ziploc bag is sealed and given to the child. The child kneads the initially soupy solution mixture and within a few minutes, the contents of the bag gels. The child is then allowed to remove the contents and play with their product. It's about the size of a golfball and can be stored in a small Ziploc container for days. I can't stop playing with mine.
I think this will be our sensory experience that day (if her teachers permit it).
