The Division of Outreach, the School of Engineering, and the CMSE at the University of Mississippi invite Mississippi students and teachers to participate in an exciting science and engineering event!
Details: The 15th Annual Catapult Competition will be held at the University of Mississippi!
Teams will compete in Design, Pop-A-Shot, Humpty Dumpty, Siege the Castle, and Art & Aesthetic.
The Spring 2023 Catapult Competition will be on April 6, 2023.
The Division of Outreach, the School of Engineering, and the Center for Mathematics and Science Education at the University of Mississippi will host an in-person Catapult Competition in 2023!!
Teams of 2-4 students in middle school and high school are invited to participate in this exciting event. The 15th Annual Catapult Competition will be held on April 6, 2023 at the University of Mississippi. Registration begins at 8:00am and the award ceremony will begin at 3:00pm.
On the day of competition, the surgical tube catapults will go through a rigorous safety check to ensure construction rules and specifications were followed correctly.
Teams will compete in 5 challenges: Design, Pop-A-Shot, Humpty Dumpty, Siege the Castle, and Art & Aesthetic. Awards will be given in each category. An overall winner will be determined from the total of the event scores.
Registration is open for teams to enter.
Deadline to register: March 23, 2023

Complete Design Specifications can be found here.

Catapults must meet all required specifications to participate in the challenges outlined below.
Design Challenge:
Design Process (25 points)
Safety Features (15 points)
Construction (20 points)
Creativity and Originality of Design (20 points)
Interview with the Team (20 points)
Pop-A-Shot Challenge:
1 point: shooting the ball beyond the basketball hoop before hitting the ground
4 points: hitting the backboard
8 points: each shot made through the hoop
2 additional points if the team can “call glass” before you shoot and bank it in the hoop off the backboard (for a total of 10 points).
4 points will be DEDUCTED if you “call glass” and make it through the hoop without hitting the glass (for a total of 4 points).
0 points will be awarded if you “call glass” and miss the backboard and the hoop.
Humpty Dumpty Challenge:
1 point awarded for each Humpty Dumpty knocked off the wall.
Siege the Castle Challenge:
1 point is awarded for each box that has moved more than half its thickness. (for example, a box must move 6 inches forward or backward from its original position. No box will be counted until the end of 5 minutes.
Art & Aesthetic Challenge:
This challenge is about decorating your catapult. You may choose to decorate the catapult in anyway (painting, drawing, adding decorative items, etc.) in order to make it look aesthetically pleasing. *Paint and decorations cannot interfere with the safety of your catapult.
OVERALL COMPETITION WINNERS:
Teams will be ranked based on the number of points they received. Ranks will go only to 12th place, meaning 12th place and beyond will all be ranked at 12th place. Sums of the ranks from each of the challenges will determine the rank for the Overall Score.
Teams will be asked about their use of the Engineering Design Process.
Deadline for Registration: March 23, 2023

We are advocates for innovation and challenging the process, so the general answer would be yes. However, if you have any questions, contact us and we can provide clarification and guidance. Always remember that safety is key!
Yes, ball bearing are allowed for the competition.
There are no specific restrictions other than it being an elastomeric tubing with a maximum length of 6ft. This is a key “engineering” decision for the teams. Workout bands are acceptable since they are tubular in shape.
Tennis balls will be used for the entire competition.
The maximum height from the ground cannot exceed three feet while the throwing arm is in its rest vertical positions.
Just to clarity, the catapult will be measured in “rest” position with the surgical bands relaxed. Generally speaking, the 3 feet restriction is the maximum possible height the catapult measure.
For example, if you are using a stop bar to control the launch angle, it would be the maximum angle, the catapult at rest, and measured to the top of the launch cup.
This requirement means that the machine will have one end of the surgical tubing connected to the throwing arm and the other end of the surgical tubing connected to the frame – this will provide the rotation.
As long as they are stretched linearly, it is within the rules.
Exercise bands are acceptable as they are probably more accessible to many than surgical tubing. We are specifically looking for tubular elastomeric materials for the potential energy, not necessarily latex or surgical
Absolutely, any commercially available off the shelf parts should be. We are more concerned with it meeting the safety requirements than necessarily what parts you choose. As an engineer, we could not in (good conscience) limit your ability to be creative.
We don’t necessarily count against teams for cost, but it is a consideration for designs that are close during judging.
It may be a good idea to separate out the form and function costs. For example – make a value assessment of the catapult with and without the extra cosmetic parts, meaning one assessment with the fancy paints and props and a separate assessment that is the actual catapult (everything the catapult needs to fully function).
This is one of the key additions to this years catapult design specs. You cannot stand directly next to your catapult and need to be able to release the catapult from 36 inches “from the plane of action”. This is the plane that launch arm rotates in, so basically you need to be able to release standing 36″ from the side of launch arm. Footholds (less than 2ft from the side of your catapult) can be added from the main body of the catapult and will not count against the maximum 36″ requirement.
