Re: 2019 National Tournament: Cornell University

What do y’all think of Solon invitational, is it a big invitational? Definitely large. I think my brother just forgot it tbh. Thanks...one more question: is Solon or Centerville the better invy to go to, if one had to pick? Depends on what you are looking for... Solon runs B and C same day, but in ...

Re: 2019 National Tournament: Cornell University

It's hard for a lot of teams to come east because of how expensive it is, the 7 hour flight from cali, the time difference, just for an invitational - especially if the team needs to spend a lot of money to go to nationals the same year. Those difficulties apply to East Coast teams as well. It's st...

Re: PICTURES, SCORES, VIDEOS!!

First post (and maybe last) in a building forum, but this is just because I happen to know what the second place boomilever score for Div. B was. It was around 2700. Low of 2663 and high of 2775. I can't tell you definitively because my teammates said conflicted things on how much their boomilever ...

Honestly, yes... I expected something north of 2400 for B and C to win it.

So... Inquiring minds want to know... What was winning B / C scores at Nats and what did it take to medal?

Re: Unofficial Rankings B

I thought this was a joke..what happened? '08 or thereabouts, Solon HS lost a Nationals bid because of this. it's a cautionary tale, now (lol i almost called it a "warning story" before realizing that wasn't the actual phrase) Rumors abound... but I've heard that Solon kids are no longer ...

Re: Unofficial Rankings B

FWIW, Solon took 1st place in 13 of the 23 events at Ohio State Competition. They are as close to unbeatable as it comes, barring a total melt down, or getting half the team stuck in an elevator. Tower Heights has been severely under-rated. I expect them to finish top 10 as well.

Re: Boomilever B/C

Let’s say I use a super low viscocity glue to connect my tension members and the round dowel by the hook. If the super glue soaks down far onto the tension sticks, will the tension members strength be damaged resulting in a break right below the connection of the dowel and the tension members? Usin...

Re: State Boomilever scores

Ohio Div C: 1st Place was 2,083
Ohio Div B: 3rd Place: was 1,650 (Not sure what 1st and 2nd was)
At Ohio State they hand load, which may be why these scores are not as high as expected.

Re: Crime Busters B

Is a handheld microscope allowed as a "hand lens"? Having run this event for several years, I have never been "tested" on this one, but I think I would differentiate between a hand lens and a microscope. A hand lens is a single lens of varying strength... from 5x to 30x or more....

Does chromatography solution affect a test differently than water would? I usually use water but states had a separate glass of "chromatography solution" to use. Does anyone know how to make such a solution? To the best of my knowledge, there is no specific chromatography solution. It is ...

Re: Boomilever B/C

Hey guys, wondering if y'all have had experience with baking boomilevers. I haven't tried it yet, but it seems like the wood would warp due to the different resulting moisture content and weaken my already-glued joints. Plus, I used Gorilla glue in a few places and it says on the bottle that gorill...

Re: Dropping Sand

its still important to keep the bucket str8 relative to the ground though, if it is tilted then the sand may tilt in the downwards direction of the bucket, later offsetting the weight distribution of the entire thing. you always want to keep things as level as possible Unless there is a sudden chan...
