How about hard boiling some eggs and getting the kids to decorate them.
Play some games like monopoly or twister or take them to one of those indoor activity places, the one with the chutes and the balls, my wee boy loves them and the added bonus is it tires them out lol.
Hard boil some eggs and show them how to decorate them. As in painting them and making faces on the eggs. Also stick some cotton wool on them for beards.
That sometimes keeps kids amused for a while.
