The pressure inside the bag or canister causes the container to break, creating an explosion that releases the pressure. but no matter what you call it, an explosion is a great way to have fun with science. But the elephant's toothpaste experiment speeds the process with a catalyst, a chemical compound that increases the rate of a given reaction. .". Chemical reaction or change: a change that leads to the transformation of one substance into a different substance. Is this the funniest animal picture ever? http://www.alka-seltzer.com/as/student_experiment.html, Learn more about the history and science of fireworks: Easy science experiments can still have impressive results! Cary, NC 27513, Copyright © 2020 Science Fun. Nope, it's straight to the Iron Man look. There was a problem. Remember: dry ice is just frozen carbon dioxide. Instruct students to squeeze as much air as possible out of the bag without tipping over the film canister. http://www.stevespanglerscience.com/experiment/original-mentos-diet-coke-geyser, Explore more cool experiments using Alka-Seltzer tablets at: Combine something sugary (like this ill-fated gummy bear) with potassium chlorate, add a little heat, and boom — you've got a rapidly unfolding oxidation reaction. Then have students very carefully place the open film canister in the other corner of the bag without causing the water to spill. Low explosives are those that burn only at their surface. Sep 3, 2020 - Explore STEAMsational's board "Exploding Science Experiments", followed by 27036 people on Pinterest. • What are other ways that explosions are made other than through a chemical reaction? Make sure everyone stands way back from the soda bottle. (Actually, the other runs probably yielded that, too, albeit as a fine haze). Challenge student to use the same materials (water, film canister with lid and Alka-Seltzer tablet) to propel a film canister into the air like a rocket. 10) Hydrogen combustion When hydrogen and oxygen are bound together in a ratio of 2:1, you get one of the most important molecules on Earth: water. .". This lesson plan was created by the New York Hall of Science in collaboration with Science Friday as part of Teachers Talking Science, an online resource for teachers, homeschoolers, and parents to produce free materials based on very popular SciFri Videos to help in the classroom or around the kitchen table.

What To Do … Pour the baking soda slurry into the soda bottle quickly and step back. If stirring be omitted until the maximum turbidity is attained, the slightest agitation results in a detonation that demolishes the apparatus.

Otherwise, prepare your space for spills and clean ups. How long do most species last before going extinct? Alka-Seltzer tablets are composed of sodium bicarbonate and citric acid. It is only if the gases they produce are contained that they cause explosions. Although scores of violent detonations have occurred, with resultant demolition of much apparatus, no personal injury has been suffered.". Discuss with students the reaction among the ingredients inside the bag. The technique is heavily used by both military and law enforcement purposes; not only detecting explosives but also having use for identification of drugs. As one overtakes the other, the color suddenly changes. Open a brand new 2-liter of soda. Usually, Hostetler said, the elephant's toothpaste experiment creates an oozy concoction. This is another good project for middle schoolers to do outdoors. The New York Hall of Science is a science museum located in the New York City borough of Queens.
