Directions:
- Tape the short end of a flexi-straw to the bottom of a Solo cup so that the tall end stands up straight in the middle of the cup.
- Fill the cup 1/3 of the way with water and freeze (ours froze overnight).
- Once completely frozen cut the cup away from the straw. I also read that you could loosen the ice by running warm water on the outside of the cup but I found it pretty easy to just cut the cup and slip it right off.
- Use a hole punch to make a sail for each boat. We used construction paper. After the fact I thought it would be cute to have had him decorate the sails but they get wet and ruined fairly quickly.
M was really excited to put them in the water and we liked sailing them back and forth and sending them down M's pool slide. As I said, the sails were soaked within a minute or so and slumped but M didn't care and eventually just pulled them off. The straw was great because he could use it to move the boat around without grabbing the ice every time.
The weather wasn't overly hot today but warm enough for this activity. That was probably in our favor because I could see these melting super fast on a very hot day. Ours lasted maybe 10 minutes each today. I made two and we played with one at a time because, of course, after the first melted M was asking for more. M actually seemed to enjoy them most once they melted a bit and were smaller. He's a big fan of throwing things (balls, rocks, etc.) into water so he had tons of fun throwing the smaller ice chunks into the water then finding them. This was a great activity for summer and one that definitely gave me some ideas for other things to try this summer!
