tapping the side of a soda can will prevent its contents from foaming over?

tap the top... not the side

If it is on the can....Just do it...Geeshhhhhhhhhhhh!!!

use bicarbonate of soda,its short term though

Actually, this can happen with any dense material, not just mentos.   Like the twisted tab of the can of coke...\n\nYou see, soda is a supersaturated solution of CO2 in water.  That means, there is way more CO2 in the water than there should be at the given surrounding temperature.  This is achieved by forcing the CO2 under high pressure.  Anyway, a supersaturated solution is unstable and is prone to destabilize with the acting of external forces... like a dense material sinking to the bottom of the solution.  This results in the eruption of excess CO2 into gaseous form.\n\nThis has worked for me a lot.   Take a standard 300 mL bottle of Coke.  Open the bottle, and quickly twist the bottle cap (to make it denser and to allow it to fit through the bottle neck), then plunge it into the bottle.  And , fooosh!!  You'll get your eruption.  Take note that you have to do all this quickly, because if you don't the gas in the bottle will escape pretty quick and the above phenomenon won't be observed.

put a bottle (like a coke bottle) in front of it.\nthat should work usually does for me.

The gas is turned into liquid by compressing it and well mixed up with water. When we shake the soda it turns back to gas and hence needs more room than it has.

Good Morning!  I saw your question and had to try this one.  A few years back I worked for Stanley Hydraulic Tools and the discharge pumps we sold we centrifugal pumps as well.   These pumps as yours are designed to move large volume not pressure. Closing the discharge side off should not damage the pump.....housing or impeller.  We had a hydraulic motor that spun the pump/impeller.  The hydraulic motor was constantly bathed in oil and even in a stall or a closed discharge valve situation the pump was protected.  I would encourage you to find out who the manufacturer of your pump assembly is and make this question out directly to them but I hope this in its self helps!  Hyway.

Water will.  Soda has dissolved compounds that will lower the freezing point.

Best when the cup can surround the can including from the bottom. Also, keep in mind your hand transfers heat into the can so if you plan on holding the can have the cup underneath.\n\nBesides, if the cup were on the top, each time yon wanted a sip you would have to remove the cup with your other hand, which is very inefficient of your time and energy.\n\nYou need to look at the entire problem not just from the perspective of the can sitting there.

Let someone else squeeze and pop it!

I've never tried this or heard of it being done, so ask your teacher if it's safe to try this experiment. Take a balloon that has a good long neck on it and force it into the tab opening of an empty aluminum soda can. Then blow the balloon up as hard as you can so that it expands to fill the inside of the can and forces all the air out of the empty can (which really wasn't empty because it had air in it!) Continue to pinch off the neck of the balloon with your fingers so the air won't come out of the balloon. Now fill up a big tall kitchen pot or the sink half way and turn the aluminum soda can upside down completely into the sink or pan of water until the top of the can and pinched off balloon are partially submerged under the water. Now start letting the air out of the balloon gradually and watch the bubbles come to the surface of the water. When all the air is out of the balloon, it still has atmospheric air pressure inside it which keeps the can from being crushed by the atmospheric air pressure of the air in the room above the water level. So try to pull the balloon out of the soda can gradually while making sure to keep the soda can tab and balloon openings under the water level. Results? Does the can get crushed by atmospheric air pressure? Of course, we always have about 14.7 pounds per square inch of atmospheric pressure at sea level. You may have to experiment with different container types that your teacher says are safe to experiment with and one that had the globular shape of a blown up balloon would allow the air to be pushed out fully. You should wear good safety glasses in case any other container (like thin plastic) rather than the aluminum container shatters in the process of imploding.\n \nPS,  Using a wider mouth container, like the aluminum soda can with it's top sawed off, you could pull the balloon out quickly even when it was blown up with air. Don't cut yourself on any sharp metal edges though. The metal or plastic container material can't be too strong and thick because it can't collapse easily then under the force of the atmospheric air pressure.

use a can of compressed air

Keep it covered to contain its flavor.

pepsi in a can for some reason

You know how when you suck on a straw you get your drink to move up through the straw? This happens because by sucking, you are creating a partial vacuum on one side of the straw, and the atmospheric pressure on the liquid on the other side, now having nothing to counter it, pushes the liquid up through the straw. But no matter how much you suck, you cannot reduce the pressure on your side of the straw to less than zero (i.e. a complete vacuum), and as such there is a maximum height to which you can raise a column of water - that height depends solely on the atmospheric pressure on the other side of the straw. This means that you can construct a barometer simply by having a glass tube immersed vertically in some liquid, and pumping out all the air on one side of the tube, and then sealing the tube - the height of the liquid then gives you the ambient air pressure. Water, however, is not very dense, and so your barometer would have to be very large if it used water. To get around this problem, scientists use Mercury, which is a much denser liquid, to measure the pressure. A pressure of 1 mm Hg is simply a pressure that can support a column of Mercury 1 mm high under this arrangement.

Hi. If you took a large can that could be sealed with a cap and put a small amount of water it, then heated the water until it boiled and was steaming from the top, then sealed the cap, the steam would condense. This would allow the outside pressure on the can due to the atmosphere to crush the can right before your eyes.

dont hang upside down and drink pepsi from a can
