We are actively investigating this at the University of Utah. This would allow for mobile PAPR units to be used in cases of need and stationary care to be provided by supply air systems. This is already in use in industry and available from 3M (1) and others though it can be custom-made too. This supply is typically at 55 l/min and with a pressure regulator and splitter can be piped to several care team members. The solution then is to use widely available air supply lines found in many ICUs and Operating Rooms. The headpiece itself may or may not be in short supply, though that is able to be custom-made or production can be ramped up easily. However the protective feature is the positive air flow, and using non-contaminated air for that flow. There is a great deal of focus on PAPR and concern about the limited supply of the air purifying unit. I am more than happy to help in coordinating such an effort, and I hope this could also serve as an inspiration in other institutions home or abroad alike. To take it one step further, official collaborations between US and Chinese institutions could also be made to set up direct supply support. Given China's slow but promising recovery from the pandemic, and more importantly, the power of manufacturing and production, I am hopeful that in ways big or small, contributions can be made in order to address the dire shortage of PPE in US hospitals. But I have been wondering if a coordinated effort can be taken leveraging the presence of international students at major US academic institutions. Some of my colleagues and I have been organizing at our school a small supply drive from our family and friends at home to our University hospital. The collaboration and ties between the two countries run deeper, especially in trying times like this. But as an international student whose family and loved ones have just gone through arguably the worse phase of the outbreak, I cannot stop but thinking about ways my home country could contribute.

In this experiment, the air pushing up from underneath the paper is strong enough to overcome the weight of the water pushing down on the paper. While we cannot feel it, the air is heavy! The weight of the air pushing down on all objects on Earth is the same as the combined weight of three cars! The reason we don’t feel this extreme weight is that the molecules in air push evenly in all directions – up, down, sideways, diagonally. The reason this experiment works is because of air pressure! Air pressure is the weight of a column of air pushing down on an area. Upside Down Water Glass Video How Does the Experiment Work? Do you know why this happens? Find out the answer in the how does this experiment work section below. Step 5 – Remove your hand from the bottom and watch in amazement as the paper stays covering the glass and the water doesn’t spill out.
