One small portion of this event will occur outdoors.  This is a scavenger hunt — be smart, resourceful, and vigilant.  MoMath cannot be responsible for your safety or offer any provisions since you are beyond the walls of the Museum.  Take care to avoid dangerous areas and situations while out and about.

Frequently Asked Questions:

  • How long will the scavenger hunt take?  Technically, you could complete the entire scavenger hunt in a couple of hours.  Alternatively, you could work on the hunt on and off throughout the weekend.  The host, Steve, framed it as a “48-hour buffet you can visit at any time.”  There are about 20 activities for the 48-hour period.  You won’t be doing activities the entire weekend.  You can take breaks and return to the hunt on the following day.  You will earn points for every task completed.
  • Will I need to go outside or travel for the scavenger hunt?  The majority of the scavenger hunt (99%) is indoors.  One activity might ask you to balance rocks, which you can access outdoors.  If you do not have access to rocks or do not want to go outdoors, you can skip this activity.
  • Does the hunt involve any physical action or activity?  There may be an activity or two that invites you to get into a yoga pose or do a dance move!
  • Does every player need to register on their own device?  Use one device for the whole team to share.  The device should be able to capture photos and videos (e.g., smartphone or tablet).
  • Can players log on and come back anytime, as many times as needed during the window of play?  Yes!  You’ll need to use the code provided via email to log back into the game.
  • Is the event fee per location or per individual?  The $15 fee covers one team in the same location, allowing for exactly one Zoom and one GooseChase connection per team.  If your team would like to log in with multiple devices and/or play together from separate physical locations, each separated player (i.e., the player(s) with an additional device or in a different location) must purchase his or her own event registration to reserve the additional Zoom and GooseChase connections.
