How do these giant balloons work? What makes them both easier and more complicated than a normal-size balloon?

MIT engineers designed a new type of gastric balloon that can be inflated and deflated as needed. It could offer an alternative for people who don’t want to undergo more invasive treatments such as ...

I forced air inside, stretching the rubber. The air inside the balloon is at a higher pressure than the air outside the balloon, and it is trying to escape.But it can’t get through the rubber of ...

This also means that the pressure is lower. This is why the balloon in the freezer shrank. At higher altitudes the weight of the air particles above the climber is less and the air is thinner ...

T-DOC ® Air-Charged™ disposable catheters use tiny pressure-sensing air balloons to assess internal pressures. Barely larger than the diameter of the catheter itself, these balloons offer ...

Beijing regularly deploys fighter jets, drones and warships around Taiwan, and occasionally balloons, as it keeps up military ...
