ge·o·des·ic dome: noun, a dome constructed of short struts following geodesic lines and forming an open framework of triangles or polygons. The principles of its construction were described by Buckminster Fuller (from Google definitions)
We were snowed in yesterday, with snow too deep on our street for our van to drive through, and temperatures too cold to allow for outside play. I decided it might be a good time to build another geodesic dome.
We built one five or six years ago out of rolled up newspaper, following instructions we found on Instructables, but my two youngest girls (ages 8 and 10) were too young then to get to help with the construction.
This time we didn't have any newspaper handy, so we settled for gluing together craft sticks (we have plenty of those left over from our popsicle stick house phase) into 58cm and 62cm long sticks.
30 - 58cm long sticks, and 35 - 62cm long sticks.
Which, sounds like a lot of gluing of sticks...
...but in reality was a quick and easy, line 'em up and glue 'em together, type of process.
We built the bottom of our dome first - a decagon base with 62cm sides...
After the base was complete, we constructed the top - a pentagon base, again with 62cm sides...
...for 5 triangles, sharing 58cm sides, rising up from the corners and meeting above the center.
The girls held the top in place, over the base, while I quickly connected the two with a series of triangles with 58cm and 62cm sides, alternating with triangles of only 62cm sides. It sounds more confusing than it is - honestly. Red lines in the picture below indicate 58cm sticks, with black for the 62cm long ones.
The girls were thrilled with their "reading cave".
