Eggstraneous uses

I know someone out there will have the perfect answer to this, so: what other uses are there for Easter egg dye tablets — the cheapie kind that come in the Paas egg dyeing kits?  It seems to me there should be SOMEthing else fun I can do with them.  Dye wool yarn on the cheap?  Paint a modern masterpiece?  Turn a public fountain or a mighty waterfall Ty-D-Bol blue?  I DEMAND TO KNOW!  Yield to me your collective wisdom, O Denizens of Ye Olde Internets!
