Presented by Lucretia Strange, Baroness Strange

Impress friends and enemies alike!  Display all of your fantastic technology props and marvel at the exhibits! Show off your jet packs, communicators, steampunk guns, robot arms, goggles, and any other weird science you’ve managed to dream up!

We encourage prop makers of all levels to participate, including children! This is a celebration of creativity.

  • Submissions: Entries should be dropped off between 10 AM and 11 AM Sunday morning.
  • Please reach out to Lucretia Strange if you need to arrange a different drop-off time.
  • Viewing: The Faire will be open to all convention attendees 11 AM to 1 PM Sunday.
  • Retrieving Items: Please pick up your items between 1 PM and 2 PM.

Things to consider:

  • We do not accept purchased items, but modified purchased items are welcome! (For example, a repainted Nerf gun.)

  • Someone will always be in the room, but we cannot guarantee the security of devices left unattended.

  • All convention rules regarding unsafe devices are applicable for the science fair. In addition, common sense shall be applied. The Promethean Society reserves the right to refuse a submission we feel is unsafe. Please direct any questions to Lucretia Strange.


Lucretia Strange (aka Cassie Beyer) heads the Promethean Society, a secret society of intellectuals dedicated to improving the world whether the world appreciates it or not.
