Let your little leprechaun find both a rainbow and treasure with this St. Patrick’s Day science activity.
St. Patrick’s Day Science Set Up:
- gold coins
- liquid watercolors
- baking soda
- pipette or dropper
- container for coins
- container for vinegar
- Place the gold coins on the bottom of a pan, and top the coins with the liquid watercolors. Spread the colors out so they don’t all mix together.
- Cover with the pan with baking soda.
- Place vinegar in a separate container.
Then it’s time for the coin hunt! Use the dropper to drizzle vinegar on top of the baking soda. As it fizzes and bubbles, the colors underneath will appear. And finally — the gold!
When we were done with the dropper method, we poured a bunch of vinegar over the pan to watch some major bubbles. (If you go that route, beware that a mess is a definite possibility! Also, vinegar stings, especially on cuts and fingers that rub eyes).
In these pictures, you’ll see my little guy sticking his face right up to look at the “rainbow bubbles.” It’s probably not a good idea to let your kids get that close – especially when the reaction first happens. He’s looking at the tail end, when the activity was kind of winding down.
