What happens at a Journey to STEAM party?

  1. Welcome and warm-up. Your party host arrives early, sets up, and gets every guest building in the first five minutes.
  2. The big challenge. Kids team up on the main build or robot mission, with your party host coaching every table.
  3. Test it. Races, stress tests and showdowns. Loud, proud and a little competitive.
  4. Show it off. Every guest shows off their build and takes home a badge. Then cake is yours.
