We just can’t get enough of dry ice at Halloween. It’s perfect for many bubbling, spooky science activities. One favorite demonstration is the Dry Ice Crystal Ball Bubble. This activity will have your audience oohing, ahhing, then asking to do it again. First, purchase a few pounds of dry ice at your local grocery store. Bring gloves and a styrofoam cooler with you. Be careful – dry ice is -110 degrees below zero and can burn skin.
Cut a strip of cloth about 1 inch wide and 18 inches long (an old t-shirt works well). Soak the cloth in a solution of Dawn dish soap or use your favorite recipe for making bubble solution. Make sure that the cloth is completely soaked. Use a smooth-lipped bowl and fill it half way with warm water. Using gloves or tongs, add enough dry ice to the

Halloween is right around the corner and there is nothing better than to mix up some dry ice concoctions for your Halloween party. Grocery stores sell dry ice, especially around this time of the year, so call around or visit the customer service desk in your local grocery store and ask if they carry it. Dry ice is -110 degrees and can burn if it comes in contact with your skin, so plan ahead and bring a cooler and gloves with you to the store. Also keep in mind that you must be over 18 to purchase dry ice.
Dry ice goes from solid to gas in a process called sublimation. It skips the liquid phase. Drop some dry ice in a cylinder filled part way with warm water and listen to the oohs and ahhs. The water burps and bubbles

It’s a well-known fact that Halloween is our favorite holiday at Steve Spangler Science. It’s time for spooky, bubbling, oozing and glowing science. You are never too old to love a good spine tingling scare or gross out. Children also love a good startle or ick moment. Just make it fun as to not cause them childhood traumas for therapy later on in life. I love to try out my concoctions on visitors to our house and rate their heebie jeebies factor.
Maybe you love Halloween as much as I do and you are designing a haunted house in your basement, backyard or garage this season. Grab those kids and science materials and invite the friends and neighbors over for a frightfully good time. Here are my haunted house ideas for Halloween decorations, activities and props.
There’s just something amazing about dry ice – the solid that turns into a gas. Science teachers call it sublimation… kids call it amazing. Over the years I’ve presented a number of television segments about using dry ice to make Halloween even more fun – Screaming Ice, Bursting Smoke Bubbles, Spooky Apple Juice, the Crystal Bubble. This segment featured on the NBC affiliate in Denver is one of my favorites… probably because of the three little helpers.
The crew from Modern Marvels on the History Channel visited our science lab back in July to play with some really cold science experiments. In other words, the liquid nitrogen was flowing and the onions were exploding! Mark your calendars… Modern Marvels: Deep Freeze will officially be airing on the History Channel on Tuesday, September 25th at 8pm EST.
