Enginearring Dazzie kids by Tureing Dull Gray Titanium into Colorful Jewelry

摘要

"Enginearring" was developed for the University of Washington's Engineering Open House in 2004 and 2005. Audiences learn how electrochemistry creates thin titanium dioxide films on titanium, why the transparent films look colorful, and walk away with unique titanium jewelry (earrings or rings). It has been incredibly popular (thousands served) and memorable (this year, some visitors told us they'd been hearing about it all year). It requires a one-week time commitment to prepare and host an open house, but kids and parents will love it. The following recipe describes the procedures we developed. Variations on this recipe are possible.
