Kids set a good pace and, using all the swagger they can muster, get across the two-by-four balance beam in no time.You can simply lay an 8-foot-long two-by-four on the grass. Or you can raise it on 6-by-6-by-12-inch blocks: Drill a hole through each block using a paddle or forstner bit and attach to the underside of the beam with long lag screws. Sand corners, and cushion with pillows.
would be fun to do as a relay. The first kid starts with a full cup of water, then pours it over his head and the second kid catches it and repeats and they keep doing this to see who can fill up a jar the fastest
