*Teams are required to have a trigger as part of their device, and you should work on this trigger earlier than later, as it can be more difficult than you might expect!

Here’s the part in the rule packet mentioning the need for a trigger:

2. The launching force must be supplied by elastic solids (springs, rubber bands, etc.) or by gravity.  No explosives or liquids may be used (see #7). Students are not allowed to use their hands (or any body part) to hold the launching arm in place.  The device must be ready to ‘fire’ without being touched in any way by the student other than to trigger the device. All stored energy must be released by a trigger on the device.  For example, a student may not pull or stretch elastic or similar powered energy sources or hold other stored energy and then simply release it themselves – the device must store any energy and have that energy be released with a single triggered action by a team member.
