Safe Fire-Free Ways to Have a Blast With Your Children This Fourth of July

Fireworks are off-limits in many areas this summer because of the fire threat it poses to foothills, forests, and even neighborhood underbrush.  Even if fireworks are allowed in your area, you’re bound to have some children who want an exciting hands-on experience, but aren’t quite old enough for the fire power yet.  Here are three fun fire-free “blast-off” experiments you can incorporate into your Fourth of July Festivities.  And you don’t even have to wait until dark!

Canister Rockets

I’ve yet to meet a child who doesn’t love film canister rockets!  Check out my instructions on how to construct them.  You’ll also find how to make this extra special by adding a little color.  When you’re done blasting off, you’ll have a colorful fireworks mural!

Good Old Steve

Mentos and Diet Coke have become a classic!  There’s a tool that makes Steve Spangler’s Mentos Geysers even easier.  Check it out!

Rocket Balloon

This is a big favorite around our house!  All you need is a straw, a balloon, tape (painter’s tape or masking tape works best, but as you can see, I’ve used a few different kinds), string, and two anchors (chairs, trees, poles, people, etc.).  First, run the string through the straw.  Next, attach each end of the string to your anchor object.  Chairs seem to work best because you can tie your string and then scoot them back to tighten your line.  Third, blow up the balloon (but leave it untied – just pinch it) and tape it to the straw, with the neck of the balloon pointing away from the direction you would like the craft to move.  Finally, let go of the balloon and watch it fly!  

Experiment with different amounts of air in the balloon.  How will it change the distance travelled?  Compare the flight of this balloon to another that is simply let go without a string as a guide.  A great science experiment, and a lot of fun!  You could also amp up the festivity factor by adding streamers to your straw and/or balloon.  (I’ve also wondered about adding glitter inside your balloon, but I haven’t tried it yet.  Let me know if you do!) 

These activities not only offer a fire-free blast, but also create science discussions about propulsion, pressure, force, and movement.  How could kids not get excited about learning?

(*You could also use these activities as part of a space or transportation unit!  Or for any other day you want to have some fun exploration!)

Have a safe and sane Fourth of July!

  1. Great ideas! I used to do the film canister thing in my Household Chemistry class at the SC State Museum. Never failed to get the kids’ interest!!
