Create an obstacle course.
Think dog agility, but take it up a notch. Get those kids moving and get out that energy. Take sofa cushions and pillows and things that won't break or cause harm, and create a fun course for them to run around. They can jump over things, crawl under things, crawl through things...use your imagination and let them use theirs, too.
There should be much laughter all around. See who can do it the fastest, who can knock over the least amount of things, just make it fun.
