Good morning! Yesterday, in a rare after dinner lull, we tackled this little crowd pleaser of a project: Fireworks in a Jar. I’ll throw it over to Katy to set the mood:
Pictures are mediocre because it was late, but go to this blog where it looks much prettier and is probably explained better too. As always, materials and set-up are Simple Simon:
- glass jar
- food coloring
- water (does that count as a material?)
Please, y’all… it was 6:00, so if you think I’m taking on anything complicated, you need to go back and read some earlier posts! Fill your jar 3/4 full with warm water.
In a separate container, pour a few tablespoons oil and add some drops of food coloring (we did 3 or 4 drops of each color). Gently stir the food coloring so the larger drops break apart into smaller mini-drops.
Pour the oil/ food coloring mixture into the jar of water and behold. Ta-da!
Read Jenae’s blog if you want the real science-y explanation, but it involves the idea that food coloring and water don’t mix with oil. All three of the kids were mesmerized. (Well maybe not Martha but she was just happy to have a seat at the table.)
It gave our whole gang a little peace and quiet after dinner as they watched the ‘fireworks’ in the jar. We did it twice and both times they were transfixed by the slow mixing of colors in the jar.
And then they lost interest. (That’s Oliver’s plastic comb… he likes to be camera ready whenever possible.)
