Inspired by this, we had a ton of fun with shaving cream fireworks. We filled plates with shaving cream, red and blue paint, and blue glitter.
We read some great books: Good Night, America by Adam Gamble and Suwin Chen, Hats off for the Fourth of July! by Harriet Ziefert, and Olivia forms a band by Ian Falconer.
We also tried Water and Oil Fireworks. But they didn't work for us, really. See the halfhearted smiles?
We introduced the girls to sparklers, and I was more excited about them then they were.
