Take the Challenge

Calling all witches, sorcerers, animagi, seers, and other members of the wizarding community. Grab your wands and start practicing your charms. We challenge you to use your inner magic to create a Harry Potter-inspired invention. You can...
  • Show us your best spell
  • Recreate your favorite scene
  • Build a magical animatronic creature
  • Forge an enchanted tool
What dark secrets of invention will you uncover?

Need some help getting started?

Use the Invention Cycle to get going:

Invention Cycle
CREATE: Brainstorm a few ideas, pick your favorite, and create a prototype.
Think about your favorite scene from one of the books or movies. Are there flying cars? Flying creatures? Large chess boards? Sorting ceremonies? Play with some ideas in your head and build a prototype (or three!) with your Bits. Don’t worry about getting everything right on the first try. The important thing is to just get started and experiment. Here are a few directions to get you started:

PLAY: Give your prototype a test run.
Is it fun to use? Does it conjure the magic you wanted? Test your invention with friends or your family to see what they think.

REMIX: Try adding or subtracting Bits or materials to see if it improves your invention.
How can you make your enchanted invention even better? Use the feedback you received from your testing to improve it. Experiment with new materials, Bits, spaces, or spells.

SHARE: Show your invention to the world to inspire others.
Upload it! Create a short video showing us what it does and explaining how it works, then submit it to the Magic of Invention Challenge.

Let the inventing begin!
