Valentine Aerogels!

The team at Aerogel Technologies has come up with a new monolithic aerogel product that integrates optically-active materials into an aerogel architecture, demonstrates aerogel shape control, and attracts the opposite sex all in the same material envelope.  Indeed, pink-heart shaped aerogels are now available on BuyAerogel.com.

Although these aerogels are silica-based, you can make colorful aerogels of your own by following the procedure for lanthanide oxide aerogels under the Make section here on Aerogel.org.
