By way of explanation, the pot in the middle is sugar water. They wanted to look at some wasps up close (don’t ask) and since Plan A (chase them and catch them with bare hands) proved unworkable though had some interestingly dramatic effects on the hysteria levels among adults in the immediate vicinity, I suggested Plan B, which was to attract them in and watch from a safe distance. They thought the wasps would be more likely to come if they thought the pot was a flower, so they asked if they could pick some petals from the garden to put around the sugar water. It looked so pretty I just had to take a picture.
