Indestructibles is a brilliant site and it's so inspiring!

Under the headings are:

• Everything
• Technology
• Workshop
• Living
• Food
• Play 
• Outside

The ideas are interesting - and sometimes even practical.  It's not just how to make or adapt the items show, but more it's a different way to view things.  I now use a different angle to view problems which need solutions (as opposed to problems which can be ignored), and even think of how to use items which would normally be thrown away. 

There are so many ideas ...  here are a random few:

Swiss army key ring

VHS tape bracelet

juice carton bird feeder

and life skills, such as how to insert a cord into swimming trunks (so they stay up!)
