What toy can I make using household items for kids 6-12 years old?

If they are 6-12 years old they are old enough to make the toy themselves with just a bit of parental guidance. If you've got the room for it you can make a cardboard castle with a washing machine box (appliance stores are happy to get rid of them) or multiple boxes bolted together. You can use half used cans of whatever paint is in the basement to paint them. Older kids could use a utility knife to cut windows. I've seen this done with a refrigerator box, opening up the box so it could be stored flat and have it set up like a staggered storefront.

You could have them build a puppet theater and make puppets from old spare socks and buttons, fabric scraps, etc. The kids could write a script and reall plan a show.

you can do at home science experiments (get a book on ideas, but one is to pour some vinegar into an empty water bottle, fill a balloon up with a little baking soda with a funnel, carefully attach the balloon to the neck of the bottle, keeping the baking soda end flopped over so the baking soda doesn't fall in, then lifting the baking soda end up so the baking soda falls into the vinegar, causing a big fizzy mess and making the balloon inflate from the gas produced. Hope that made sense.

You can make rag dolls.

Kids that age are often interested in cooking; teach them to cook. Not a toy, but something to keep them busy and fun to do for kids.

A lady at work gave me this idea the other day. If you go to a store like wal mart or kroger or whatever sometimes you can find these little bitty like mini bottles of water that are kinda shaped like rocket ships. If you peel the label off the kids could put paper on them or paint them to decorate them. And it will encourage them to drink water!!

let them make their own toys - they will have more fun making them than playing with them!

you can make anything with a cardboard box.

Paper dolls there easy to make and fun!

damn, what is you poor?????
