Why glycerin in bubbles

Soft water is good for bubbles. Hard water, any water containing high levels of iron, including well water is bad for bubbles.

If you live in an area with hard water and are having difficulties making good bubbles, try using distilled water available at the grocery store. Objectives Make a bubble and understand its structure. Materials See each recipe for details. Key Questions Why does soap create a film? Bouncy Bubble Solution You can bounce these bubbles off your clothes!

Add the shampoo and glycerine and stir gently. Reheat carefully in the microwave about two minutes before using as this solution will gel as it cools. Polyethylene oxide is a cool polymer that helps bubbles self-repair and therefore helps bubbles stick around a lot longer before they pop.

Stir the solution until it is mixed together. You can use the solution right away, but to make even better bubbles, put the lid on the container and let your super bubble solution sit overnight.

The addition of the glycerin or sugar makes the bubbles last longer before popping. Glycerin can be purchased at most health food stores. Glycerin makes stronger, longer-lasting bubbles, but corn syrup is often substituted in bubble solutions because it is cheaper.

Distilled water will provide best results but you can substitute with regular tap water if needed. If you live in an area with hard water and are having difficulties making good bubbles, try using distilled water available at the grocery store.

Propylene glycol is a colorless, odorless liquid with similar humectant, or moisturizing, properties to glycerin. Also known as PG, propylene glycol is commonly used as a glycerin substitute in cosmetic and toiletry products because it is typically cheaper. By adding glycerine or cornstarch you are changing the evaporation rate of the water. When soap molecules mix with water molecules, they tend to separate out small bits of water to form bubbles.

Soap molecules have two very different ends: one end attracts water hydrophilic and the other end repels water hydrophobic. A bubble! Soap bubbles can help to solve complex mathematical problems of space, as they will always find the smallest surface area between points or edges.

A bubble can exist because the surface layer of a liquid usually water has a certain surface tension, which causes the layer to behave somewhat like an elastic sheet. Adding glycerin to the water and dish detergent helps make the bubbles last by slowing down how quickly the bubbles dry out. Sugar also makes the bubbles last longer by not letting them dry out as quickly.

Glycerin, also known as glycerol, is a thick, transparent and non-toxic liquid that is commonly found in soaps. Glycerin is a natural by-product of the saponification process.

When oil reacts with alkaline, it forms soap and glycerol. However, we only use a food grade, vegetable-derived glycerin in our soap making. Unpoppable bubbles are bubbles made from corn syrup and dish soap that last longer than average.

If you want to make unpoppable bubbles, you can do so with a few ingredients and supplies. After mixing your ingredients carefully, you can blow fun bubbles to play with as you wish. Magic Bubbles Catch and Hold takes your bubble fun to a new level! The special solution in this test tube produces bubbles that harden in the air. Gently blow through the bubble tool while holding it in the air for a line of bubbles.

Wait for a few seconds after the bubbles have formed, allowing them to harden. Evaporation isn't the only thing that pops bubbles. Anything dry can pop them. When a bubble floats through the air and lands on your finger, on a blade of dry grass, the wall of your house, or your pet's fur, the bubble will pop. When something sharp and dry touches the bubble, it pokes a hole in the bubble's skin, all the air goes out of it, and the bubble disappears! To learn how to touch a bubble without popping it, do Trick 2 in the Bubble Tricks experiment.

Bubbles that float in the air and are not attached to anything are always round because the thin wall of soap is pulling in while the air inside of it is pushing out.

A bubble always tries to take up the smallest amount of space and hold the most air that it possibly can. A sphere, the round ball shape of a bubble, is the best way to take up a little space and hold a lot of air.

Even when a bubble starts out as a square or another shape, like in Trick 1 from the Bubble Tricks experiment, it will always turn into a round sphere as soon as it floats away into the air. A square bubble would take up more space than a round one. There are a few times when bubbles are not round. Sometimes the wind blows them into different shapes. When bubbles are surrounded by lots of other bubbles, the ones in the middle get squished into other shapes, like squares or hexagons shapes with six sides.

Try blowing a lot of bubbles right next to each other in a shallow container and see if there are any that are not round. If you pop the bubbles on the outside, the ones on the inside will not be squished anymore and they will push back out to round bubbles again!
