4th of July Science Projects

Here's a recipe for a density column that's a layered cocktail. It's perfect for the 4th of July or Memorial Day or pretty much any holiday with a red, white and blue theme. You can add gold liqueur for 'fireworks' glitter and you can set the drink on fire.

Make a waterfall firework that shoots out a river of fire, falling in glittering sparks 20-30 feet. This is an easy project that produces a cool effect.

If you've got fireworks, you've got smoke. Why not collect some of it to shoot smoke rings? This project works with colored water too.

This isn't specifically a science project, but if you make your own fireworks it is important to know how to light them safely.
