What causes a marshmallow to expand?
When heating a marshmallow in a microwave, some moisture inside the marshmallow evaporates, adding gas to the bubbles. In addition, a warmer gas pushes outward with more force. Both adding gas and heating cause the gas bubbles to expand, thereby causing the marshmallow to puff up.
Do marshmallows expand in hot chocolate?
Let the hot chocolate cool completely and place a marshmallow in it. Let the hot chocolate cool completely. Freeze a marshmallow and use a fork to poke holes in it and place the marshmallow in the cold hot chocolate. Let it sit for half an hour as the marshmallow expands, a little.
What happens to marshmallows in hot chocolate?
Hot chocolate is simply incomplete without marshmallows. The hot chocolate’s energy seeps into the marshmallows and “jiggles” the sugar and protein molecules. That’s when the molecules separate and the marshmallows turn into those blankets of goo and dissolve into the drink.
How do you make marshmallows bigger?
If you heat the marshmallows in the microwave, the microwave heats up the water. The hot water heats up the sugar, which makes it softer. The hot water also heats up the air bubbles, which makes the air bubbles get bigger. The air bubbles push against the sugar and water and the marshmallow gets bigger.
Can u eat a microwaved marshmallow?
Leave the other marshmallow on the plate and watch it for a minute. When it shrinks back down, you can pull it with your fingers and make it into whatever shape you want. It will stay in that shape and get hard and crunchy. You can eat it, too.
Why do marshmallows get bigger inside a vacuum?
Under normal conditions, molecules of air from the atmosphere (called atmospheric pressure) are pushing on the outside of the marshmallow. When the vacuum packer removes the air that was once pushing on the outside of the marshmallow, the air trapped inside the marshmallow pushes out (expands) causing it to get larger.
What happens when you put 30 marshmallows in a huge vacuum chamber?
Marshmallows have small bubbles of air trapped inside them. These bubbles are at atmospheric pressure. The air bubbles inside the marshmallows are therefore at a much higher pressure than the air surrounding the marshmallows, so those bubbles push outwards, causing the marshmallows to expand.
What happens to marshmallows in space?
Answer 2: One answer:Marshmallows have quite a bit of air whipped into them during the manufacturing process. As the pressure decreases as you go into space, the gas inside the marshmallow would expand, sort of like a balloon being blown up. At some point, the marshmallow would explode, just like the balloon.
Is there a lot of pressure in space?
In space, outside of the Earth’s atmosphere, there are almost no molecules in the gas that surrounds the International Space Station. The absence of molecules, means that the air pressure is extremely low – in fact it is almost zero, so it is nearly a perfect vacuum.
Why do you die in space?
The vacuum of space will pull the air from your body. Without air in your lungs, blood will stop sending oxygen to your brain. You’ll pass out after about 15 seconds. 90 seconds after exposure, you’ll die from asphyxiation.
Can astronauts eat marshmallows?
Astronauts Used Marshmallows As Nose Plugs With marshmallows pushed up their nose, the fluffy snacks expand in cabin decompression without the astronaut’s nose sustaining damage while still allowing them to breath.
How do female astronauts pee in space?
To use it, astronauts sit around the hole just as we would on Earth, poop, wipe themselves and then put the wipe inside the hole. The same suction system that uses airflow to keep urine from flying out of the funnel also works to keep all of the “deposits” inside the toilet.
How do you pee and poop in space?
To pee, they can sit or stand and then hold the funnel and hose tightly against their skin so that nothing leaks out. To poop, astronauts lift the toilet lid and sit on the seat — just like here on Earth.
Do astronauts shower?
On the ISS, astronauts do not shower but rather use liquid soap, water, and rinseless shampoo. They squeeze liquid soap and water from pouches onto their skin. They use towels to wipe off the excess water. An airflow system nearby quickly evaporates excess water.
