After running to Home Depot for some missing pieces, our team just finished building our first Tetra tonight! It took us about half an hour of build time. The Tetra is actually pretty cool, a little larger and heavier than you'd expect, but cool nonetheless. Fairly strong if you super glue the PVC pipes.
BTW. Use gumdrops instead of hot glue. It goes faster and you'll have a mock field to work with in under half an hour. And if you have trouble with people eating them, dip the gumdrops in Tabasco sauce.
