Some of the past challenges have become buried in the archives, but until I have time to redo (and figure out) my sidebar, I thought it would be helpful to post direct links to some of the building challenges in one place.
Here they are:
**Build a Tower**
**Use your Noodle**
**Suspend As Many Marshmallows In The Air As Possible**
**Elevate an Apple**
**Finally, a cure for the common cold!**
**Door Jamb Span**
**Create an Ornament**
**Ice Cold Colors**
**Build a Tower that Won't Topple**
Don't forget to check the archives if you want to see photos of how other teams solved these challenges. And, if you try these out with your team, let me know -- I'm always happy to add photos so that others can be inspired by you!
