I told DH what I wanted for my birthday, but I told him I also wanted to have a surprise to unwrap on the actual day. It turns out we were camping on the beach on my birthday and he did surprise me. He got me a bubble shooter. I had a ball shooting bubbles into the tress. After a few minutes we could hear the children in the other camps yelling about the bubbles.
The grass was wet so when they landed they didn't pop right away.
