I want to have a combined birthday party for my son and ss, ages 10 & 5 since their birthdays are only a few weeks apart. I want it at our house, and there will probably be around 20-30 kids total between family, school friends, and other friends. Any ideas on cheap activities I can do to keep all those boys busy? It will be mid september in the midwest...so may be hot or may be cold outside. I was thinking of maybe some type of obsticle course/ sports activities in our yard? Any ideas for easy team games?
I was also thinking of maybe some type of science experiments because they are both on a science kick lately and love mixing liquid soaps with juices and stuff to see what it looks like. Any ideas for easy, kid friendly experiments for them all?
Thanks so much!!
