Now that Griffin's 10, he gets to go to Webelos. On his 10th birthday, they toured our local fire station where they got to try on their clothes and use the hose.
They were also working on the Scientist activity badge and part of that was building and launching rockets. Since we were out of town while they did it, we put his together the night after we got home from our vacation. And the best thing was that even unpainted and put together with scrapbooking glue, his was the only one that made it through without some level of destruction, so he got to launch it twice!
