What prevents the water balloon from popping?
Water is a great substance for soaking up heat. In fact, the exchange of water happens so often that it keeps the balloon from popping . . . until the heat of the flame is greater than the water’s ability to conduct heat away from the thin latex and the balloon pops.
Why does the balloon with water did not break in the flame?
When water inside the balloon is placed in the flame, the water absorbs most of the heat from the flame. Because the rubber does not become hot, it does not weaken, and the balloon does not break.
Why did the air filled balloon burst while the water filled balloon remained intact?
When you fill a balloon with water instead of air, the water absorbs most of the heat, so the rubber doesn’t get very hot. Water has a very high heat capacity, much higher than air, so it will keep the balloon from bursting.
What causes a water balloon to pop?
The air inside the balloon pushes really hard on the melted part and makes the weakness get bigger, so the balloon pops. When the balloon is filled with water, the water absorbs the heat. This stops the balloon from melting.
Will a balloon filled with water float?
Warm water is less dense than cold water, so the cold water in the water balloon was more dense than the hot water and so sank. As the water cooled down, it’s density increased making the balloon float again.
Would a balloon pop in space?
Unfortunately, no. There would be no popping sound in this space-balloon experiment, as sound waves require a medium to move through. In space, the air molecules would still expand outward, but without any air in a vacuum, there is no “sound barrier” to break, per se, so it would be a completely silent pop.
How high can a helium-filled balloon go?
Helium balloons rise because helium is lighter than air. And according to the U.S. Fish & Wildlife Service (FWS), helium-filled Mylar® balloons can rise as high as five miles above the earth. That’s more than 26,000 feet.
Were there any female aeronauts?
Some of the most famous aeronauts during this period were women: Margaret Graham, Jeanne and Élisa Garnerin, Louise Poitevin and Sophie Blanchard. They traveled around Europe with their husbands making all kinds of spectacular ascents.
Was there a real Amelia Wren?
Amelia Wren, Redmayne’s pilot in The Aeronauts, is a fictional character invented by screenwriter Jack Thorne. She is based on Henry Tracey Coxwell, who saved Glaisher’s life after the meteorologist passed out on their record-breaking ascent into the sky.
