Rat Racer: Described

Greg asked if there was a video of Danny’s Rat Trap Racer in action. There is not. Danny accomplished his mission in AP Physics, but when showing the racer off in another class, the front end was snapped off by the repeated blows. With a 96 grade on file, Danny tossed the racer in the trash. (He’s not a pack rat like his Dad.)

With no video available, I can only describe what I saw in our hallway and our driveway during test runs the night before. I also want to offer this clickable front view of the racer:

Sleek, huh?

In early tests in the kitchen the racer had some design problems. Danny tied a single string to the trap arm with the other end to the rear axle. Danny would wind the string and set the trap. By dropping a pebble on the bait lever, the trap would violently spring, spinning the wheels. The car would move a foot or two, and more often than not the string would be broken.

After many experiments, three modifications turned the Rat Trap Racer into an amazing machine.

First, Danny stopped tying the string to the axle. I told him how my Grandfather, Papa, used to wind a string around a top and throw it. This solved one problem, because the string was being rewound on the axle, acting as a brake.

Second, he added duct tape along the edges of the rear CD wheels. This gave the wheels much better grab, especially on slick surfaces.

Third, Danny put two strings on either side of the arm and either side of the rear axle. Instead of the arm violently snapping, it would close in a more controlled way, allowing the car to accelerate to top speed.

By this time, the hallway was far too short to contain the speedy Rat Trap Racer. Final tests were conducted in the driveway where the racer zipped along some 30 to 40 feet on an upward slope!

The teacher has video of Danny presenting the physics of the Rat Trap Racer. I hope to get my hands on that and provide a transcript.

Dear Mary Claire,

I have been waiting for this tooth for a long, long time! I did not know you were going to lose it in Florida. I’m glad it did not fall in the sand.

Your sister saw me when she lost her fifth tooth, so you can, too. Only she thought she was dreaming, so you might think that, too.

Have a fun vacation!

Love, T.F.

One For The Fans

Danny’s rec league team, the Braves, had their ups and downs this season, but somehow they managed to go into the playoffs ranked first. (Danny couldn’t figure that out.) There were four teams, so they would have one play off game and one final game. The Braves would play against the Cardinals who had several of Danny’s friends on it, including the good hitting / pitching / first-base combo of John M. and Scott S.

Gramalie and Grandad came out for what turned out to be a perfect evening for baseball. It was clear and cool. Kathy and I were also there while the girls were at Sunday school.

Danny put on a great show for his four biggest fans. He started off as catcher with Hutto pitching. Hutto pitched well, and Danny aggressively defended the plate. There was a threat at third, but they held the Cardinals to 0 runs in the first inning.

Danny bats clean up, and with one man on second, he came up to the plate. Two outs and the count went full with Danny fouling a couple of hard hits outside the third base line. One foul almost took out his coach.

We were all yelling “base hit” hoping to drive in the man on second. Danny’s last hit was a solid connection, and the ball sailed over center field and cleared the fence by six feet. Home run! Braves were up 2 – 0.

With the Hutto-Cashel pitching combination, the Cardinals reached third base all three first innings, but could not score. Danny came into pitch the fourth inning, throwing mainly fast balls.

John M. is a great hitter. He’s hit Danny twice and Danny has struck him out twice during the season. Danny was throwing great, but John got the bat on one, and hit it almost to the fence in right field. He got on second, and that would lead to the Cardinal’s first score. Danny was determined to make that the last score. It looked like he added another 5 m.p.h. to the rest of his throws, including a very quick throw over to first to catch a Cardinal trying to jump back. The first basemen was equally surprised that he caught the ball. It even knocked him off balance and he fell on his rear end (while applying the tag!)

The third man in the line, Dean A., up is very smart base runner and had managed to steal third. I told Dad how I like Danny batting behind him so he can drive him in. Danny likes to draw the throw over to first or second to generate a run. As I was telling this to Dad, Danny was walked. He ran down to first, watching the pitcher, who was not paying attention, so sure enough, Danny rounded first to draw the throw. Danny saw that even the second baseman was not positioned correctly, too far in front of second base, so he decided to go for the steal. The pitcher threw the ball to second, but Danny ran in behind him, and meanwhile the man on third scored. Score 3-1.

Danny would be knocked in making the score 4-1, the final score.

Kathy and I cannot recall a game where Danny got to do so many things in one game, so Gramalie and Grandad picked a good one to drive out for.

The next day at school, Danny and John M. were debriefing. Danny had to reschedule work to make that game, and he told John, “I’m glad I was able to show up for that one. Not sure we would have beat you guys if I hadn’t.” John said, “No kidding… you made all four runs happen!” (As if Danny didn’t know.)

2 Tooth Fairy

Dear T.F.,

Can you wake me up so I can see what you look like. I thought you said I would loose my tooth in March. Can you send this wish to the wish fairy (pretty please with sugar on top.)

Wish: I wish that there was every thing that a person wanted.

Your friend,

Kelly Elizabeth Cashel

P.S. Please always check for notes every night.

Dear Kelly,

Thank you for your note. I think you are funny and you write so well.

You have gotten so big, but your tooth was very small. You’ve had it since you were a little baby, I guess.

I looked at your brother’s new tooth tonight. Has he shown it to you? It is big, and in the back.

I tried to wake you up by tickling your nose. You just blew on me and rolled over. I think you were tired.

I will tell my friend the Wish Fairy your tricky wish. I’m sorry your tooth came out so late. Maybe the next one will come out in time next March.

Love,

T.F.
