The Rocket Story

So, Levi was selected to go to the Ohio State Fair with his "Rockets Away!" 4-H project. We're excited for him to have the experience!
I am admitting that, given the amount of time dedicated to the "presentation" or "decoration" of the rocket, I was very skeptical about any kind of award beyond an "A" ribbon. Levi kept telling me, "It's fine, mom". Somehow, I just wasn't sure the judges would appreciate the aesthetic qualities of duct tape as much as he and his father.
Of course, as it usually is when it comes to all things engineering-related, I was proven wrong. It's not that the rocket was sharp-looking in any sense, but I think the fact that Levi knew what he was talking about, had built the rocket(s), had built a launcher with Eric, and understood the science behind it all counted for a lot. The clincher, though? I can't say for sure, but my guess it was the story and documentation of the final test launches (done 2 days before judging, resulting in the need to completely rebuild a new rocket -- see picture). In the book, the requirement was just to document the height and velocity from launches with different amount of water and/or pressure. Levi and Eric decided, after 8 adventurous launches in 90-degree heat and humidity that ended with Mom running to the store for more 2-liters, that the judges should see exactly what had happened. I'll let the spreadsheet "notes" section speak for itself!

Psalm 31...fresh bread

How great is your goodness,
which you have stored up for those who fear you,
which you bestow in the sight of men
on those who take refuge in you.

In the shelter of your presence you hide them
from the intrigues of men;
in your dwelling you keep them safe
from accusing tongues.

Praise be to the LORD,
for he showed his wonderful love to me
when I was in a besieged city.

In my alarm I said,
"I am cut off from your sight!"
Yet you heard my cry for mercy
when I called to you for help.

Love the LORD, all his saints!
The LORD preserves the faithful,
but the proud he pays back in full.

Be strong and take heart,
all you who hope in the LORD.
