What happens when you combine lab experiments with Halloween activities?
Spooky science, of course!
We decided to enlist the help of Vancouver's Science World to bring some education to All Hallows' Eve.
Program coordinator Brian Anderson says it's the perfect time of year for scientific learning.
"Halloween is a great time to explore some fun science and learn a few cool things, too," he adds.
On this particular day, Anderson, along with two pint-sized assistants, demonstrated some classic chemical reactions.
Flaming pumpkins are always a hit; just don't try them at home. In this case, Anderson uses a flammable lycopodium powder derived from a type of evergreen herb.
He also manages to create a jack-o'-lantern by blowing out a pumpkin using calcium carbide mixed with water to make acetylene gas.
If you're looking for some family-friendly amusement, try putting raisins (or dried cranberries) in a carbonated beverage. It's safe to drink and kids will enjoy watching them swirl in the glass as science does its work.
Of course, it wouldn't be Halloween without candy. One of these special experiments requires yummy gummy worms, though you won't be eating these ones. Just soak some gummies in a baking soda and water solution. Spoon the mixture into a container of vinegar and the candies will continuously float and sink, creating a cool witch's brew effect.
If you have a young one interested in science, the fourth annual Girls and STEAM virtual event returns to Science World on Nov. 6 from 9 a.m. to 12 p.m. The free symposium will feature popular science speaker Dr. Samantha Yammine.
Science World is currently open daily from 10 a.m. to 5 p.m.
