Geodesic Domes

Easy science lesson for today, all you need are some toothpicks and gum drops.
Domes have been around for a long time. What makes geodesic domes different?   Efficiency!

A sphere is already efficient: it encloses the most volume with the least surface. Thus, any dome that is a portion of a sphere has the least surface through which to lose heat or intercept potentially damaging winds.

A geodesic dome uses a pattern of self-bracing triangles in a pattern that gives maximum structural advantage, thus theoretically using the least material possible. (A "geodesic" line on a sphere is the shortest distance between any two points.)
This one is made from legos.  You can make them from playdoh too.  You know the big golf ball at Epcot, that is an example of the geodesic dome.  I love easy science lessons.
PLUS, you can eat this one!

We tried those with marshmallows and toothpicks once! I am guessing though that the gumdrops might be a little bit more effective!

Thank you E.W.


Yes, they are weightier!
