Collaborative Drawing

Ok -- you must have at least two people to complete this challenge:

The challenge is to draw a picture using only perpendicular lines. The rules: you may not speak to each other before or during the challenge about the challenge and you may only draw one line at a time. The next person can only draw a connecting perpedicular line. You have 24 hours to complete this challenge.

Good luck!

Food Creation Solutions

Sayer and her brother Duncan did a fantabulous job with this challenge. They used a small can of olives, a pack of gum, a chocolate coin, and marshmallows from the pantry, 2 carrots from the fridge, and 2 sticks from the yard, plus LOTS of tape to construct a helicopter.

I misplaced these pictures so if someone can resend them -- please do and I'll post. Thanks for your patience.

Cups and Coins

Here's the challenge: build the tallest tower possible100 cups/coins -- the number must add up to 100 but you can allocate any way you wish. One more rule: cups may only touch coins, they may not touch each other. Since there is a good chance of collapse, we recommend that you use paper cups and quarters.

Good luck!
