Crazy Contraptions Day
featuring Rube Goldberg Family Speed Builds

Saturday, Feb. 29

Explore the different ways you can create chain reactions and complete simple tasks in complex ways! Imagination, humor, and teamwork are front and center during these wacky activities.

Activities include:

  • Rube Goldberg Family Speed Build: You and your family can participate in your very own speed build! You’ll have 45 minutes to trap a mouse or pop a balloon in the most complex way, using only the materials we give you.
  • Chain Reaction Virtual Reality: Build a crazy contraption using our state-of-the-art virtual reality system!
  • Use the Force Live Science Show: A Da Vinci Science Center educator will review Newton’s Three Laws of Motion in new and exciting ways! Help them debunk the magicians’ tablecloth yank trick and watch them attempt to break a board in half using their hand! Shows at 11 a.m., 1 p.m., and 3 p.m.
  • Award-winning Rube Goldberg Machines on display, made by Allentown School District students.
  • Chaos Machine: The Chaos Machine is a massive collection of tubes, tracks, motors and other widgets that can be used to move marbles around a layout that you build yourself. What makes it chaotic is that everyone is invited to modify the machine, limited only by imagination and the laws of motion.

Rube Goldberg Family Speed Build Details:

  • 12 p.m. & 2 p.m.
  • Limited space available. Pre-registration is recommended. 
  • Included with admission or membership.

Leo’s Creativity Studio: Crazy Contraptions

Running Feb. 12 through May 22

Leo’s Creativity Studio is a maker space experience for all ages! In Crazy Contraptions, explore cause-and-effect relationships using common objects and materials. Create a chain reaction contraption that triggers sequential events in fun and surprising ways. These activities promote large-group participation and teamwork to set and accomplish goals.

Chain Reaction Table

With the Chain Reaction Table, you must create a chain reaction that will ring a bell. How you accomplish this task is completely up to you! We provide the materials, you provide the solution!

Popsicle Poppers

Harness kinetic energy to create interesting shapes with only popsicle sticks! Weave the sticks together in over/under patterns to complete our four challenges. Plus, discover what happens when one stick is moved out of place!

Domino Challenge

Arrange dominoes to complete different challenges or come up with your own! Can you create a chain reaction? Can you turn one line of dominoes into two lines? Work with your family and friends to see what you can accomplish!

Leo’s Creativity Studio is supported by PPL Foundation, B Braun, and ATAS International, Inc.
