Science Project: Spooky Halloween Smoke Machine

Oct 09, 2016

What is the best part about Halloween? The costumes? The candy? Getting to roam your neighborhood well into the night? Or is it the science? Maybe science isn’t the first thing you think of when Halloween comes around, but this Spooky Halloween Smoke Machine is a fun and creative way to bring some science into your Halloween.

There’s nothing spookier than thick murky smoke creeping along the ground, mainly because who knows what is lurking beneath it. To get this smoke the best method is to use dry ice.

Dry ice is solidified carbon dioxide that unlike ice, which changes from a solid to liquid by melting, dry ice changes from a solid to a gas through a process called sublimation. Hence why it’s called “dry” ice, it never gets wet.

It’s also extremely cold at -110˚ F (-78˚ C), which makes it perfect for keeping things cold when they’re being shipped or when refrigeration is difficult. Which means you can find it at some grocery stores and even some ice cream shops. Because dry ice is so cold, if you were to touch it with your bare hands you’d get instant frostbite.

You must use gloves, tongs and adult supervision when handling dry ice.

So then, how does dry ice make such a good Halloween decoration? Here’s how:

Materials:

  • 5-10 pounds of dry ice
  • Gloves
  • Tongs
  • Warm water
  • Styrofoam cooler or pumpkin

Procedure:

  1. Using heavy-duty gloves or tongs take a chunk of dry ice and place it in your Styrofoam cooler. You could also use some organic material, like a hollowed out pumpkin.
  2. Add warm water to the dry ice. The warm water will cause the dry ice to sublimate faster and will produce more fog.
  3. To keep the effect going keep adding warm water until all the dry ice is used up.

Remember, don't touch the dry ice with your bare hands...ever!Remember, don't touch the dry ice with your bare hands...ever!

Important things to note:

Don’t touch the dry ice with your bare hands. It’s been said before, but it’s worth saying again.

Be aware that there will be more carbon dioxide present in the surrounding area of your spooky smoke machine, so best to place it in a well ventilated area to make sure you can breathe properly.

Lastly, have a spooky smoky Halloween!

Global warming will raise the ocean and bodies of waters. The cities will be flooded, and then frozen over. Someone goes outside, they freeze to death. The remaining survivors will die of starvation or freeze to death.

In my opinion, I see four most likely possibilities.  >>  Nuclear War/World Wars. >> The universe practically imploding and the sun burning us into oblivion or even another planet/meteorite slamming into us, destroying us entirely. >> Self-destructive tendencies of our own species, either accidentally or purposefully. >> Trump. Which could be the matchstick to the flame of at least two other things on this list.

I think it's kinda sad that there even actually exist debates where people argue whether someone else's identity is 'legitimate' or not. You know who knows that? The person who identifies as bisexual (or whatever else). Not me, not you, not their parents, not your parents, and no, not any religion. Them. Only them. No one else. That's it. But it is nice to see people expressing support. I'll join in and say, for all the bisexuals out there, be who you are. Let not any one person's judgment distract you from what your true feelings are. “If someone isn't what others want them to be, the others become angry. Everyone seems to have a clear idea of how other people should lead their lives, but none about his or her own.” ―  Paulo Coelho ,  The Alchemist

You cannot describe color to a blind person. But they also see things that you can't that they cannot describe to you. I have a friend, Joseph, who's been blind since birth. He says it looks sort of like nothing and everything at once, and that little dots malt into one big dot. He also doesn't quite grasp the concept of "dark" and "light" but he can sense when a light is on vs off. I have a friend who's been blind since she was eight (grenade accident) who says it's like a mix of every color, but it's not quite black or white. And there's no one color she can name of it. But when there's a noise, the "blanket" shifts around where the noise came from, like something's different but you can't tell what.

In a couple billion years, the sun will die and implode, taking Mercury, Venus, Earth, and possibly Mars with it. Unless the silent death flares get us first. They could happen at any moment with no warning, you know. Scratch that. Trump's gonna kill us.
