BTW, we also had one tower that maxed out the gram scale and had to weighed on the sand scale... I think it tipped the scale at 155 grams... Not nearly the mega-structure mentioned earlier, but still a true engineering marvel... or something like that. Still nowhere near as impressive as the guys that rolled their boomilever in on a wagon several years ago, because it was too heavy to carry... I don't think I will forget that!

Those West Liberty numbers are VERY impressive; wow.

We had one at 250gr+ that had to be weighed on the sand scale. Another interesting one in the 100gr range; the hole at the top was a 7-8cm square- as in the load block would pass through with lots of clearance on all sides. They avoided Tier 3 by putting the load block into one corner- so supported by 1 leg, and the top ladders, and the puppy went to full load- and they asked (it ran late in the day) if they could put more sand in. Stopped at 22kg, and was still holding.

We had 5 or 6 others, I think, that... neglected to consider the 8cm circle; a couple by a tiny bit, some massively; one very indignant, that there was nothing in the rules about anything like that

One of our tier 2 towers was built in a triangle shape, without any taper. This obviously violated the 80 mm rule as well, but we really wanted to see them test it, so we allowed them to adjust and readjust, until the block was barely supported by a corner of tower, while the chain barely passed within the 5 cm center circle. The loading block was barely on the cross beams, but somehow it stayed there and if I am rememering correctly, actually carried a full load. This was the 155 gram tower though.

Is this real? Would work out to ~5.8g holding everything at 70cm. That's National gold worthy. Can anyone here confirm that score?

seems right... sadly.... :/ is walterpayton school in A or AA *hoping for AA*

EDIT: it seems that they aren't even going to state, *phew* though i am very impressed with that. that just goes to show that nationals doesn't always have the best devices in the nation, just the best devices in the nation of the teams that made it to nationals, you could technically put together a super-team from around the country of people in events that didn't even make it to nat's and they'd win every event.

It also goes to show that Science Olympiad is a team effort, and that one amazing event will not get you to the next level. Nevertheless, 167 is amazing, great job Walter Payton!
