Birthday parties · Grades 1–8
The party they'll build
Every guest builds a real engineering project with real tools and takes it home. Three hours on a Saturday or Sunday afternoon, led by our instructors. You bring the cake; we bring the engineering.
- $950 for up to 15 kids, the birthday child included
- $50 for each extra kid, up to 40 in all — billed after the party
- Saturdays and Sundays, 3–6 PM — come up to an hour early to set up
- Guests sign up and sign our waiver online, so check-in is instant
- Final kid count due 2 weeks before the party, so we can prep project materials — kids signed up after that aren't guaranteed to be able to build the project
- Paid in full when you book, and non-refundable
What's included
- An instructor-led, hands-on engineering project
- Real tools and all safety gear

- A finished project for every guest to take home

You bring the cake, food and drinks (nut-free, please), plates and cups, and any special decorations.
