In honor of the 4th of July, here are 4 fun science links:

4th of July Science Projects is a list of 10 great ideas for homemade patriotic science fun! I especially like the dark Snakes recipe because it’s so much fun to light them and watch them squirm and wiggle!

Steve Spangler recently published an experiment on how to make Colored Smoke Rings in honor of Independence Day. So cool!

You can make Exploding Bubbles when you check out this NPR special. Theodore Gray explains how to mix hydrogen, oxygen, and soapy water to make really neat explosions. He’s also the author of the book Mad Science, which I’m adding to my wish list; it’s all things that go bang!

For some reason when I think of cool things related to the 4th of July, the second thing that comes to my mind after fireworks, of course(!), is a potato gun. If you’ve never used one, you’ve got to try it! SpudTech is a website where you can purchase potato guns, but it is always way cooler to build your own.
