Thanks for that Chris. The tetrahedral kite is one of the first kites I ever built, and had success flying on the first try.
My plan for this includes: 1 box drinking straws, 1 pack tissue paper, 1 spool thread/small string, 1 tube stick glue, 1 spool kite string... A tail is a good idea if the wind isn't steady.
Simply "suck" the thread through the straws to make pyramids, cut the tissue paper into diamonds (with little flaps to fold over the straws) glue 1 diamond to two panels of the pyramid, tie the pyramids together. Easy, fun, and they look great on display. I tied four 4 celled kites just as in this instruction into a 16 cell, took to school to fly in the playground as show-and-tell, but it was destroyed by the class bully before I got to try it... Never made another one, but I've been wanting to make a go at it again just to say I've flown a 16 cell tetrahedral... (sounds fancy)
They look like a lot more work than they actually are, I built my 16 cell in about 2 hours when I was 10 or 11. (probably take me all day now
