We are just days away from the 4th of July and soon the skies will be aglow with fountains of fireworks and sparklers will be filling the sidewalks. But just how hot can those sparklers can get?

“Sparklers are fun because they're handheld, you don't shoot anything, there doesn't need be a lot of flame, but they can be very hot," says West Fargo Fire Department's Training Chief Matt Berg.

We tested out how hot sparklers get with the help of the fire departments thermal imaging camera.

For comparison, water boils at 212 degrees, a match burns at 325 degrees and campfires can head up to 575 degrees. The sparkler went over 1,000 degrees at its hottest.

“Probably second or third degree burns if it sat on your skin long enough so just imagine you’re cooking a pizza at 450 degrees and you open that oven up, right? And this is double that," Berg says.

So if you are using sparklers, you want to keep the weather in mind, especially the breeze.

“Stay with your wind at your back so the winds blowing away from you and sparks aren’t blowing onto you. And just be safe and be away from the house and away from the deck and kind of in your green grass," Berg says.

But even after the spark goes out, the temperature can still be above 120 degrees even 30 seconds later.

“Put them out in a bucket of water or a bucket of sand or sandbox anything like that," Berg says.

For some fun and safe alternatives for the kids, you can try party poppers or glow sticks.

The National Fire Protection Association says that sparklers alone account for more than 25% of emergency room visits for firework injuries. For children under 5-years-old, sparklers account for nearly half of the injuries.
