Colors of Spring with Baking Soda and Vinegar

Bees were buzzing and birds were singing. A few days of sunshine was all it took to get our tulips and daffodils peeking out of the ground. It was all it took to get us outside as well, soaking up all the Vitamin D our bodies could absorb. In honor of the seasonal burst of color we’ll experience soon, I set up a rainbow variation of a classic baking soda and vinegar science experiment for the kids.

The kids helped set everything up, scooping piles of baking soda onto trays while I prepared small jars of vinegar, each with several drops of food coloring and two pipettes for each color.

I was pleasantly surprised to see my kids start with mere droplets of vinegar and observing the reaction closely (they are generally known for a “more is more” approach rather than starting small). William commented that the bubbles left behind from the vinegar fizzing in the baking soda created holes that looked like craters.

But after a while Sara decided that using one dropper at a time just wasn’t enough…

If one works well, I wonder how three at a time will do?

Without any interference from me, this beautiful mess appeared on William’s tray:

Everything is more fun when you can do it outside. Unable to resist the urge for instant springtime, I bought a Costco-sized flat of colorful primroses.

I’m so glad I took a few pictures of their colorful heads after we planted them because this is what they looked like the following morning:

CHOMP!

I would have suspected our resident banana slugs (we grow ’em big out here) or the little cotton tailed bunny we’ve seen hopping into the salmon berry brambles recently but when I counted that 12 primroses been chomped to smithereens and a few had even been uprooted from their comfy holes, the evidence unmistakably led to deer. Note to self:  just because you don’t see the deer around these days doesn’t mean they aren’t dropping by in search of the next pretty flower to bloom.
