On our second night swim Granny and Poppy put the glow sticks inside the balloons. Ahhh, tricky tricky.
It was pretty cool. And they all just really wanted to pop the balloons. But they held out for a pretty good while. Until it was time for us to go and then the got to pop all the balloons and collect their glow sticks prizes :)
Also it was really nerve racking because I couldn't see Cameron very well and kept thinking he was drowning. But he was always fine.
