We had a mostly clear day at the Mayo Event Fields in Stowe for the thirteenth annual Vermont Pumpkin Chuckin' Festival with 9 teams competing in the chuck, 4 teams in the Chili Cookoff, 3 food trucks, 31 volunteers and over 1000 spectators enjoying the chuckin', chili, food, band, kid activities, volleyball tournament, games and a tortoise roaming the field. We believe we have the longest active running trebuchet contest in the US. Over $14,000 was raised for the Clarina Howard Nichols Center (Morrisville) whose staff and volunteers did an amazing job running the festival. The Clarina Howard Nichols Center is doing great work combating domestic and sexual violence and they did a fantastic job running the festival for the fourth year in a row!
Two new event records by the Stapleton dynasty and their amazing “Walking Arm” design: Once again the Stapleton family with their unique “walking arm” trebuchet design dominated the competition with 2 new event records in both the middleweight and heavyweight divisions. Because their design is superior and Jonathan Stapleton was nice enough to put up a tutorial on how to build and scale their design on instructables.com, their design was copied by most of the other competitors, only 1 floating arm design, 1 King Arthur design, and none of the 1000-year-old standard design were represented, whereas in the first festival (2009) ALL of the trebuchets were of the standard 1000-year-old design. Check out the past year's festival summary below to see how the design and best distances have evolved from 2009 to 2022.
Jonathan Stapleton's Walking Arm Trebuchet threw a 5 lb. pumpkin 798 ft.
Why the Walking Arm design is the best in the world:
The current world record for throwing an 8-pound pumpkin with a trebuchet is 3,377 feet set in 2019 by Colossal Thunder at Punkin Chunkin, Rantoul, Illinois. This is a staggering accomplishment, but they were not limited by height and weight like our festival. By limiting the height and weight in each division we ensure that each competitor has exactly the same amount of potential energy, so their success or failure comes down to efficiency in design and implementation. The theoretical maximum distance a trebuchet can throw is 2 x (weight of trebuchet) x (height of trebuchet) / (weight of pumpkin). In our competition a heavyweight trebuchet is limited to 500 pounds (total weight) and 10 feet (height) so the theoretical limit that a heavyweight trebuchet can throw a 5-pound pumpkin is 2x500x10/5 = 2000 feet. This is theoretical because we are ignoring air resistance, friction and assuming that the arm and frame weigh zero and all 500 pounds is in the counterweight. Jonathan Stapleton’s heavyweight threw 780 feet out of a possible 2000 so its efficiency is 780/2000 or 39%. Colossal Thunder’s height is 24 feet, and the counterweight alone is 5000 pounds so the theoretical limit it can throw an 8-pound pumpkin is 2x5000x24/8 = 30,000 feet. Since it threw 3,377 its efficiency is 3,377/30,000 or 11%. If Colossal Thunder design was scaled down to compete in our festival in the heavyweight category it would throw 228 feet. If Colossal Thunder actually entered our heavyweight competition their 3,377 feet throw would have been “adjusted” for being overweight and over height to make it fair for the other competitors. Since we weigh the total trebuchet, not just the counterweight, Colossal Thunder would be awarded less than 190 feet assuming that their frame and arm weighed at least 1000 pounds. This is not to say that Colossal Thunder isn’t a laudable marvel in its own right — merely that in our engineering-focused competition it can’t measure up. Another indicator of the walking arm’s efficiency is the movement or lack of movement after the pumpkin has left the trebuchet. The arm simply falls to the ground after the throw. This shows that almost all of the potential energy in the counterweight has been efficiently transferred to kinetic energy in the pumpkin. Colossal Thunder’s arm and counterweight are still thrashing around long after the pumpkin has left indicating lots of wasted energy since all the motion of those heavy parts had to come from somewhere. By measuring efficiency, the walking arm design beats Colossal Thunder by 39% to 11%.
First annual Vermont Pumpkin Chuckin' Invitational Volleyball Quads tournament:
Ryan Rabidou promoted and ran a volleyball tournament with ten teams during the festival gathering the best players in Vermont and New York. The winners of $100 cash prize were Ryan Rabidou, Nick Pizzuti, Alex Richard, Jeremiah Ward. Second place went to Carter Peck, Shawn McBride, Lauren Brough and Michala Dean. Next year Ryan anticipates a much bigger tournament with as many as 20 teams.
Dolores the Tortoise:
Kelly Carrick brought Dolores, her well-behaved 30-pound tortoise to enjoy the festival. During the 2nd round Dolores happened to be enjoying the festival directly in front of a huge catapult preparing to fire a 5-pound pumpkin. Kelly was alerted to the impending danger and instructed Dolores to crawl out of the way. She started crawling at a glacial pace when Kelly picked her up and moved her out of harm’s way. Shortly thereafter the pumpkin fired in a line drive and rolled directly over the patch of grass that Dolores just vacated. Thirteen years of pumpkin chuckin and no people or tortoises have been harmed!
