Yes you are correct. Your device will only be considered out, if the parts that touch the floor go out of the lines.
Hello. I just wanted to check that the device needs to travel 21 feet (not 21 inches). Would Lego pieces (wheel, etc.) be considered ordinary “found objects”? Would a wheel that was 3D printed be allowed? Thanks much.
You are correct, the device needs to travel 21 feet. Lego pieces are definitely “found pieces” . The 3d printed wheel would also be allowed.
Does the mousetrap device need to by triggered by the catch? Or, can it be wound up and let go by a team member?
*One team member must trigger the device after it’s been placed at the starting line (see Limitation 8 below), so teams may NOT just hold the device and then release it or let it go. One team member must trigger the actual mousetrap ‘catch’ to start the device’s movement. This is part of the challenge for teams, to try to get their device reliable enough so that it will move after being triggered! 🙂
8. The entire device cannot be larger than 3’ high, 3’ long and 3’ wide when set-up and ready to be triggered at the starting line.
Cool creativity! There are no creativity points awarded, however, during the district meet. You could add the pinwheel if you think ‘Judges Choice’ judges will find it creative. Just make sure that the pinwheel in no way assists in the powering of the device (no wound up energy stored and released).
Limitation 1 (in packet) states the following:
- The only source of energy for each device is a single, typical mousetrap (“Victor” brand or similar type) 17/8” x 37/8”. They should be readily available at hardware and/or variety stores
Your mousetrap should closely resemble the trap illustrated in the packet (wood base, arm, etc.), but the catch may be slightly different. The trap should not be any plastic type trap (in original form or disassembled).
There is no rule saying you have to use a certain type of wheel. Please remember to be careful and have an adult make sure you’re being safe!
3rd graders can attempt the challenge, but can only register for the district meet if they are on a team that consists of mainly 4th and/or 5th graders or higher
