Keep the washers in place by tying a knot around them to secure them in the center of the string.ĥ) Tie each end of the longer string to each of the screw eyes atop the wooden dowels, just as you did with the shorter string. The washers will act as a weight at the bottom of the bubble wand frame, so the bigger the wand (and longer the string), the more washers you may want to add. You can adjust the lengths as needed but be sure the second string is approximately half the length of the first string.ģ) Tie each end of the shorter string to each of the screw eyes atop the wooden dowels.Ĥ) Slide two, three, or four washers onto the longer string. It does this by creating space between the water molecules, decreasing the strength of their attraction to. To make the string lengths manageable for little ones to stretch with their arms, make the first length of string about 60 inches and the second length of string about 30 inches. Adding soap or detergent lowers the water’s surface tension, allowing bubbles to form. Repeat with the other wooden dowel and screw eye.Ģ) Cut two pieces of string. Try different sizes of bubble wands to create smaller and larger bubbles.Here's how to put together your own bubble wand:ġ) Drill a small hole in the end of one of your wooden dowels. Make our easy bouncing bubbles recipe, no glycerin or corn syrup required! It’s such a a cool science experiment, and a fun summer activity that’s great for sensory play. Simply mix 1/3 cup of bubble solution with 2 Tablespoons of sugar. Yes, we had good luck making bouncing bubbles with dollar store bubble mixture. It’s the perfect use for a lone sock!Ĭan you use store bought bubble solution to make bouncing bubbles? ![]() The soft texture of the cotton winter gloves seems to gives extra cushion to protect the surface tension of the bubble. If you don’t have winter gloves handy, put a clean sock on your hand. Find more resources for at-home education and entertainment for all ages at. We also tried to bounce the bubbles on nitrile gloves, TPE gloves, and rubber gloves, but none of them worked! Brittany teaches you how to make a bubble wand and shares the science of bubbles. The only gloves that worked for us are soft winter gloves. What kind of gloves do you need to make bouncing bubbles? You can also use corn syrup or glycerin, instead of sugar, to make a strong DIY bubble solution. This makes the bubble stronger, and allows it to last longer. The sugar forms a bond with the water molecules, reducing the speed at which the water evaporates. This allows you to hold and bounce the bubble, but why?Ī bubble bursts when the water between the soap molecules evaporates. When you add sugar to the soap and water mixture, it creates a stronger, thicker bubble. This allows the water to stretch around the bubble. When you add soap to the water, the surface tension (the force between the water molecules at the water’s surface) decreases. Water bubbles pop very easily on their own because water is not very stretchy, and it wants to return to its original form. ![]() A bubble is formed from two layers of soap surrounding a thin layer of water, with air in the center. To understand how bouncing bubbles work you need to know a little bit about how bubbles are formed. What is the science behind the bubble experiment? ![]() The cold bubble solution should give you better bouncing bubbles, because the water will evaporate more slowly. Try comparing a bowl left at room temperature versus a bowl stored in the fridge. If you have the time, leave the bubble solution to sit overnight for extra strong bubbles.This can provide better results, because there are no extra minerals in it to stop the bubbles from forming. If you’re having trouble getting big bubbles, try using distilled water.You can also cut the rounded end off a disposable pipette, dip the cut end in the solution, and blow through the small end to make bubbles. Try making your own bubble wand from wire or a pipe cleaner.
