Colors without dyes - Hands-on science at the phaenovum Open Day in Lörrach
On the last Saturday in May, we participated in the open house at the phaenovum Lörrach student research center. Overall, it was a successful event, with many interested children, pupils and parents in attendance. In addition to providing information about studying nanoscience at the University of Basel, the SNI stand offered colorful chocolate that didn't contain any dyes.
Anyone who wanted to could use Chocofoil to give Basel Lecklerli a shimmering chocolate coating. The fascinating colors are created by microstructures on the chocolate's surface that bend light, causing the chocolate to glow through interference effects — an impressive example of applied nanoscience!
Many thanks to the fantastic phaenovum team for the great organization, and to everyone who came to research, marvel, and enjoy with us.
