It consists on painting eggs with a marbling effect technique.
This is a project that precedes the egg hunt my students are going go on with me and their PE teacher at the end of this week.
Glue a wooden skewer on (empty) egg using a hot glue gun.
Fill a plastic bowl with water. (make sure it's an old bowl that you can dye with paint)
Drop some glass paint drops into the water.
Mix the colours softly and slowly with the tip of a wooden skewer.
Finally, immerse the eggs in the water (making sure the children don't touch the paint), and pull them out slowly.
PS. I must thank my student Mariana, who, after painting her egg, was the super professional photographer documenting the entire process! So, Thank you Mariana!
