Make superhero cuffs. You can use toilet rolls or kitchen rolls, cut them once to slide onto wrists and decorate with whatever you like.
Make you own superhero mask or goggles. You can use egg cartons or draw a mask onto some cardboard, cut it out, decorate it and then attach it with string, pipe cleaners, elastic or wool. You can use cardboard from an old box or even a cereal box.
Design and make a superhero using a lolly stick. You could use an old pencil if you don’t have any lolly sticks.
If you have created a healthy menu or meal for a superhero then maybe you could make it by drawing, painting or using collage materials. Maybe you could even make your own healthy lunch!
