Two young girls holding up slime made using glue, baking soda, shaving cream, food coloring, and contact lens solution. Slime is a homemade toy typically created using a combination of water, glue, and borax. Videos of people playing with slime became popular on social media in the mid-2010s, which made it an international trend.
Baking powder is made up of a base, an acid, and a buffering material to prevent the acid and base from reacting before their intended use. [5] [6] Most commercially available baking powders are made up of sodium bicarbonate (NaHCO 3, also known as baking soda or bicarbonate of soda) and one or more acid salts.
In the experiment, a film canister is filled with water, an effervescent tablet (commonly Alka-Seltzer) is added and the canister tightly sealed. After a short time, the pressure of the carbon dioxide is great enough to cause the body of the canister to be launched into the air with a popping sound. The canister may be embellished with paper ...
Try this experiment at home with the kids to introduce them to the basic tenet of physics -- kinetics! In this week’s episode of Experimental , take your physics smarts to the next level ...
Cupcakes baked with baking soda as a raising agent. Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate [9]), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO 3. It is a salt composed of a sodium cation (Na +) and a bicarbonate anion (HCO 3 −).
A column of porous black graphite formed during the experiment. Carbon snake experiment. The carbon snake is a demonstration of the dehydration reaction of sugar by concentrated sulfuric acid. With concentrated sulfuric acid, granulated table sugar performs a degradation reaction which changes its form to a black solid-liquid mixture. [1]
Flubber (named from the film The Absent-Minded Professor), Glorp, Glurch, or Slime is a rubbery polymer formed by cross-linking of polyvinyl alcohol (PVA) with a borate compound. Slime can be made by combining polyvinyl-acetate -based adhesives with borax .
Elephant toothpaste reaction Two people watching the reaction of Elephant's toothpaste. Elephant's toothpaste is a foamy substance caused by the quick decomposition of hydrogen peroxide (H 2 O 2) using potassium iodide (KI) or yeast and warm water as a catalyst. [1]
