Are You Crazy Enough To Build One of these Things?
The first thing you need to realize is that it is not easy to build a sculpture—so be
impressed! Almost every year there are some entrants who discover just how hard it is to
build a robust human-powered amphibious vehicle because they experience some sort of catastrophic
And once you build the sculpture, you need Kinetinauts who have the physical
stamina to propel the contraption 15 miles!
Here are some helpful resources:
2020 Entry Form for
Kinetinauts. Every Kinetinaut, Pit Crew member, and
Barnacle needs to fill out and sign this form. (If you don’t know what a
Barnacle is, read the official rules again.) If you have Adobe Acrobat (any version including the free Reader) you can fill out the form on your computer if you right-click on 2020 Entry Form and choose "Save link as..." Or you can print the blank form and fill it out by hand.

Here are KineticBaltimore’s tips for your first sculpture. (Once you’ve built a sculpture, feel free to violate them.) I’ve never made a sculpture, but I’ve seen many break down:
- You’ll probably need someone who can braze—or better yet—weld. The structure needs to be held together strongly in order to survive the race. While it may seem a lot easier to assemble a frame out of PVC pipe or lumber, the frames of sculptures that make it to the finish line tend to be made of brazed or welded metal.
- Test! And test some more! Frank Conlan and Peter Stern’s team of Make Believers builds some of the best innovative sculptures each year. In 2002, they had a novel stair-stepping propulsion technique on their DeVine Stompers sculpture. In 2003, they built the Teapot, and in 2004 the Cirque de Sore Legs train. Fabulous art combines with very effective engineering with that bunch. Even then, the Cirque experienced the most exciting mishap in years of racing when it was blown off course and broke apart while being towed by the Baltimore Police. These guys are the best, and still have unanticipated excitement. So if you’re building a sculpture for the first time, you must test it thoroughly, because you don’t want to be one of those sculptures that breaks down in the first hundred yards of the race!
- Wear Costumes! Outfitting your pilots and crew with costumes that match your sculpture’s theme is essential in creating a spectacle. Don’t forget your helmets—giant pieces of meat, huge sombreros, or some other thematic enhancement to your bike helmets will make a huge contribution.
- Work the Crowd! Spectators love to join in. Especially at the water entry, one of your crew can encourage the crowd to cheer
along. If we have room, the Spectator’s Guide can include a cheer that you provide on your application form or send to us at KineticBaltimore.com.
- Plan any surprises carefully! Some teams like to surprise the crowd with a dramatic flourish—like when the It Cain’t team transformed their Titanic Ocean Liner into a rowboat on the water in 2005. You can surprise the crowd, but be sure to tip off the media so the surprise can be documented. You can email us here at KineticBaltimore.com, include a note about where your surprise will occur on your entry form, or at least send a member of your pit crew around to notify all nearby media a few minutes before you do it.
There are many more paths to calamity than success. Here are some technical tips you might want to consider from past years’ entrants:
- 2001: These guys drove into
the water at the Canton loop and immediately sank. Their flotation relied on a
little bit of gray styrofoam and some long yellow PVC tubes. But the tubes were simply
tied with twine, which was clearly not up to the hundreds of pounds of force they were about
to face—horizontally. The tubes shot forward, and the rear of the sculpture
sank like a stone.
Lesson #1: Be sure everything is held together solidly. Twine does not count.
Lesson #2: Be sure to test your sculpture in all terrain. Really test.
This sculpture had an artistically clever design—a cow with a configuration like a Conestoga wagon, and hinged cow legs
to look like it’s galloping. Bicycle wheels without tires perhaps seemed a good idea in the design stage, because
they look slightly more like wooden wheels. However, less than halfway through the race, I saw two exhausted
Kinetinauts struggling to keep the cow going. Amazingly, they explained that they had started the race as mere
spectators, and that the original Kinetinauts who designed the sculpture had gotten so worn out that they had abandoned
it to them! These recruited Kinetinauts were already tired and tried to recruit us. But The Galloping Cow
actually made it across the finish line, with conscripted Kinetinauts!
Lesson #3: If you start with an existing concept (like a bicycle)—and you probably
should your first year—don’t remove any features (like tires) without understanding
why they’re there.
Lesson #4: Never give up—even if you have to recruit strangers to drag your sculpture to
the finish line.
Lesson #5: As a spectator, you never know what you’ll be called on to do.
A reprise of Lesson #1 from above, with styrofoam and air mattresses that aren’t held together
as securely as they might be. But in true innovative fashion, these guys designed their sculpture so they were riding
backwards through the race. But despite this questionable design choice, they finished! They won the
Next-To-Last award, but they finished!
Lesson #6: The race is 15 miles. Imagine piloting your sculpture
Lesson #7: Never give up, even if you have to drive backwards! You can do it!
Louie the Dog was out for his second year through the course, a first-class veteran, and was making mincemeat of the competition
without breaking a sweat. Then he got into
the water at Canton. Some extra weight added since last year really got to Louie; he started sinking on one side.
(See the Pontoon Effect footnote at the bottom of the 2005 Race Description. Left to his own devices, Louie would have probably inverted himself, upside down and completely under water. Louie is proof that it’s
possible to win the Engineering Award one year for an incredible design,
and the next year to win the Golden Flipper Award for almost capsizing!
Lesson #8: Past performance is no guarantee of future success.
Lesson #9: If you don’t make physics your friend, it can become your enemy.
The Galloping Cow Rides Again. A picture is worth a thousand words.
Lesson #10: Tis better to race and capsize than never to race at all.
Subdude had a paddlewheel, but it was completely under water—thus useless.
Lesson #11: Paddlewheels require calibration to ensure they’re 30% to 50% submerged. Be sure to test the sculpture with the same amount of weight on board you’ll have during the race.
Kinetic Airways suffered a drivetrain failure trying to drive out of this pothole. Without a pit crew or spare parts, it couldn’t finish the race and was brought to the end of the race in a trailer.
Lesson #12: Have a pit crew.
Lesson #13: Have spare parts.
In a restaurant, tacos are good. In a Kinetic Sculpture Race, they’re often doom. Bicycle wheels seem ideal for Kinetics—but it’s quite easy
to overload them laterally. When you apply too much lateral force, they bend like a taco. Each year, at least one
sculpture tacos a bicycle wheel. You almost certainly won’t have the tools to de-taco a wheel with you, so finishing the race may depend on having a spare wheel or two.
Lesson #14: Try to avoid over-stressing your components, especially wheels and brakes.
Lesson #15: Bring spare wheels, ready to be installed.
We saw above that side-to-side forces can overwhelm a pontoon. It’s also important to balance your sculpture front-to-back.
Lesson #16: If you do just one test, make it a water test.
Your sculpture may also just totally fall apart when you hit the water.
Lesson #17: Don’t do this.
