The key thing that makes a sparkler safe is that the metals are proportioned in just the right amount. This leads to a controlled burn. Can you guess how hot a sparkler is? The human body is around 98 degrees, an oven can get up to degrees. Iron, on the other hand, melts at around 2, degrees. This is in the range of how hot a sparkler gets.
The sparks can reach from 1, to 3, degrees! You might think this makes them scary. This is because its heat is coming from its thermal energy.
Scientifically, temperature and energy are two different things. The sparklers have extremely low mass and their thermal energy is low as a result. An easy way to think about this is to consider the case of a pizza wrapped in foil in the oven. Will the foil burn you?
The sparks in your sparkler are doubly safe because of their size. If you think about it, you probably already know that small things cool off more quickly. You already know that the smaller ones will cool off more quickly and be ready to eat that much faster.
The science that determines all this is all about volume. Think about a small cube of metal. This means eight times the thermal energy. A sparkler is not dangerous, but they still produce a tiny bit of heat.
This is not usually enough to burn anyone. Still, remember to take precautions, but still, have fun! Have a look at our Ultimate Guide for Wedding Sparklers and see how this little item can take your big day from blah to wow. No products in the cart. A sparkler is a type of hand-held firework that burns slowly and emits colored flames, sparks and other effects.
A sparkler is typically made from a metal wire coated with a mix of potassium perchlorate, titanium or aluminum, and dextrin. Aluminum or magnesium also helps create that familiar white glow. Yet, according to the CPSC, the thrill of fireworks can also bring injuries.
On average, people go to the emergency room every day with fireworks-related injuries in the month around the July 4th holiday.
CPSC advises that parents closely supervise the use of any fireworks and adds the cautionary warning that sparklers should not be handled by young children. Some fireworks can pollute the environment with debris and smoke.
Pyrotechnic scientists have already begun to address some of these issues, by finding new ways to make fireworks that are more environmentally friendly, such as creating compounds that use nitrogen-rich materials or nitrocellulose that produce less smoke.
