You can find more experiments like this one at, and in my books Kitchen Science Lab for Kids (Quarry Books) and Outdoor Science Lab for Kids (Quarry Books). © Quarry Books, 2016/Outdoor Science Lab for Kids Featured Photos Credit: Amber Procaccini © Quarry Books The thickness of bubbles is always changing slightly, as are their colors due to light hitting the bubbles from many different angles, causing light waves to bounce around. But when you blow a bubble made out of dish soap, you create a very thin film of water sandwiched between two layers of soap. Water molecules like to stick together, and scientists call this stickiness “surface tension.” Soap molecules make it harder for water molecules to stick together. Step backwards or move the wands to create giant bubbles. You can “close” the bubbles by moving the sticks together to close the gap between strings. Both wands will work great with this bubble recipe. ![]() The washers will act as weights for your bubble wand. Pull the string up out of the bubble mix and pull the sticks apart slowly so that you form a string triangle with bubble in the middle.ħ. Before we visit the GIANT Bubble Wand (also shared in the video below), I just want to mention that we have some super duper CUTE beaded bubble wands for you to check out. Thread a few washers on the 5-foot rope before tying off the other end. With the two sticks parallel and together, dip bubble wand into mixture, immersing all the string completely.Ħ. Tie remaining 18 inches of string to the end of the first stick to create a triangle.ĥ. Put a washer on the string and tie the string to the end of the other stick so the washer is hanging in-between, on around 36 inches of string. Tie the string to the end of one stick.Ĥ. Around 54 inches of cotton kitchen stringģ. 1 Liter (1/5 gallon) of (hot) tap water, 250ml (1 cup) of GOOD quality washing up liquid/ dish soap / dishwashing liquid (in the UK the Fairy Liquid brand really is best) 2-4 tablespoons glycerin.To make a giant bubble wand, you’ll need: Use immediately, or stir again and use after an hour or so. Add remaining ingredients and mix well, without whipping up tiny bubbles. ![]() Things as small as a piece of dust or pollen will pop the biggest bubbles These are often the unseen forces that will pop your big bubbles when just the day before you where making monster size bubbles that would last and last. (I'd prefer not to specificy a brand, but the type of detergent can literally make or break your giant bubbles.) Dawn Ultra-not concentrated, or Dawn Pro are also highly recommended. When anything dry touches a bubble, it will pop. glycerine (Corn syrup may be substituted for glycerine.) Amanda Rock, mom of three, has spent more than a decade of her professional career writing and editing for. To make a bubble solution using vegetable oil, mix 1 cup of water, 4 tablespoons of dish soap, and 2 to 4 drops of vegetable oil. It’s simple to help kids whip up a dish soap bubble mix at home, and you can make wands for blowing giant bubbles with a few sticks, some kitchen twine, and a metal washer.įor best results, try this experiment on a day when it’s not too windy. Some people prefer this option because vegetable oils are more readily available. Science comes into play every time you blow a bubble, and giant bubbles are double the fun.
