Happy 4th of July!

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 Black 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.

  1. The colored smoke rings blown into the air are really something – I want to try that.

    Here in England I don’t think we have the smoke bombs though. What are they? Can people just buy them in the stores?

    Here’s a recipe to make smoke bombs: http://bit.ly/ZWdPq

    Basically, they’re just a little object with a fuse. When the fuse is lit, a chemical reaction occurs, causing a lot of smoke to result. Definitely an outdoor activity! Sometimes the smoke is colored, but it can also be just white.

    I’m not sure if they sell them in England either. I never thought to ask when I lived there. In the USA, it depends on what state you live in, but most states have fireworks stands in the summertime where you can purchase small smoke bombs along with other fun things to light on fire!
