Today was the Valentine’s Day Party for our little school group. C’s second time making and giving Valentines and he was again confounded by the idea. Then he got into it, and at the party he carefully dropped one Hershey Kiss and one Valentine in each bag/box.
One of the Valentines was a small balloon that inflated itself with a chemical reaction (I opened one with the kids but we couldn’t identify out the liquid). You initially smack it to burst the tiny bag inside the balloon and mix the chemicals and then the whole thing would pop to life. Had all the kids waiting (at a safe distance) with bated breath.
