Your challenge: raise an egg off the ground as high as possible using the following:

The Tall Ships

Kis Who Think

Using the following materials, build a sail boat with the tallest mast possible. Make sure it floats (or sails). Send video or pictures.

3 cereal boxes
3 cardboard tubes
6 plastic spoons
tape
6 pennies
3 straws
6 sheets of paper or 1 yard of fabric or a garbage bag

– Aluminum cans

Posted: 28 May 2009 03:00 PM PDT

Place three cans (soda cans are easier to work with but other cans will work) on the table along with some paper, tape, and string. Tell your students to make something, anything.

They may use scissors or other cutting utensils during construction IF SUPERVISED (this is pretty dangerous and it is easy to cut yourself). Scissors may not be a part of the solution.

When they are done, but not before, show them this and this and this!

These are really cool!
