Painting, bubbles, what’s not to love?! A simple chemical reaction with loads of excitement! Materials Liquid watercolour paints Vinegar (in the clear container) Baking soda Liquid watercolour paper (or cardstock- something thicker is better for younger kids) Containers Spoon Paint brushes Pencil/eraser Tray We always find a smock helpful too! Directions Don your smock. Draw and cut out a shape you would like your paper to be or skip this step if you like! Dilute your paint with vinegar. Paint your paper. While your paint is wet, sprinkle on your baking soda and watch for the bubbles. Play with adding more paint and baking soda. Allow your work to dry and gently tap or brush off any excess soda. (It is hard to see in the photo, but in the sunlight it has a iridescent shimmer in the sunlight!) Hang up your work! (This was a good way to sneak in some math- patterning the beads with two attributes: size and colour! A shoelace is a perfect lacing material for beads.) Purpose Learning about chemical reactions. Safety Notes We suggest that you wear a smock and use a craft tray to protect your clothing and surfaces.
