Why not use cardboard boxes to recreate famous film scenes like these parents have. Not only is it a lot of fun during the making process, but it can also lead to hours of fun while reenacting the scenes.
Cut up your cardboard boxes so that they are flat and then begin sticking the sides together so that you create a maze. Hide things in the maze - The first to find them all wins!
We've all been there - Take a selection of cardboard boxes and tubes and tape them together to make a selection of rooms and turrets. Then hide and get ready for attack.
Take two cardboard boxes and cover them in tin foil. Cut some eye holes in one and some arm holes in the other. Ta-da, you have the perfect robotic disguise.
