How many triangles?
This is the latest fad in our household.... K'nex. The boys received a small set for their birthdays, and they quickly fell in love. I managed to find a teenager selling his huge boyhood Knex collection for a pittance (bless you, Craigslist!!), then Alfie realized Knex had motorized sets and got into it as well, and all of a sudden we've got quite a haul!
Since this weekend's Photo Hunt theme is Triangles, I asked one of the boys to build me a 3-D diamond. Can you tell me how many triangles you can find in the structure? I've lost count!
