Two eggs that were dyed


Have you ever dyed eggs? Turning eggshells from white into different, dazzling colors can be a lot of fun! People often do this using dye tablets to make different colors in a liquid bath. They then dip the egg into the liquid and wait till it turns the desired color. Eggs can be dyed in many other ways, and one neat method uses silk ties. Sounds strange to use clothing to dye eggs, right? But it actually works really well! In this activity, you will dye eggs with silk ties and investigate whether heat is needed for the process to work well. Are you just dye-ing to try this out?

  • 100% silk tie. Look at the tags on the back of the tie to make sure it is 100%. Darker blues, purples, and reds transfer dye the best. These ties can usually be purchased at a secondhand shop or thrift store. Be sure to ask permission before using someone else' silk tie for this activity! The ties will be destroyed in this activity.
