Diet Coke and Mentos eruption

The experiment became a subject of the television show MythBusters in The eruption is caused by a physical reaction, rather than any chemical reaction.

The addition of the Mentos leads to the rapid nucleation of carbon dioxide gas bubbles precipitating out of solution: The conversion of dissolved carbon dioxide to gaseous carbon dioxide forms rapidly expanding gas bubbles in the soda, which pushes the beverage contents out of the container. Gasses, in general, are more soluble in liquids at elevated pressures. Carbonated sodas contain elevated levels of carbon dioxide under pressure. The solution becomes supersaturated with carbon dioxide when the bottle is opened, and the pressure is released.

Under these conditions, carbon dioxide begins to precipitate from solution, forming gas bubbles. Normally, this process is relatively slow, because the activation energy for this process is high.

The activation energy for a process like bubble nucleation depends on where the bubble forms. It is highest for bubbles that form in the liquid itself homogeneous nucleation , and lower if the bubble forms on some other surface heterogeneous nucleation. When the pressure is released from a soda bottle, the bubbles tend to form on the sides of the bottle. But because they are smooth and clean, the activation energy is still relatively high, and the process is slow. The addition of other nucleation sites provides an alternative pathway for the reaction to occur with lower activation energy, much like a catalyst.

For instance dropping grains of salt or sand into the solution lowers the activation energy, and increases the rate of carbon dioxide precipitation. People with knee pain are often steered toward these bikes, since the impact of body weight is not a concern as it is on a treadmill, elliptical trainer, or stair stepper.

But to avoid knee strain, you must make sure the bike is adjusted to fit your body, Vukovich says. Most people sit too low, meaning their knees flex too much as they pedal. This can put too much pressure on the knee and result in soreness, warn Vukovich. The stationary bike is a less intense calorie-burner than some of the other machines. You'll need to pedal four miles to burn calories, says Alexander.

Rowers are more advanced cardiovascular machines. Because you must push with the legs while you pull with the arms, rowers require coordination. They also you require you to engage your core abdominal muscles to support and protect your back. Because they use so many muscle groups, rowers burn lots of calories.

But this machine has several red flags for a beginning or unfit exerciser. Extra weight often comes with back pain , and this is not a machine you want to use if you have back issues, he says.

Choose a machine that feels right. If impact is a problem, the stationary bicycle may be a better choice than the treadmill. More muscle use equals more calorie burn. The basic rule of thumb is that the machine that exercises the greatest muscle mass burns the most calories.

There's a flip side of that coin, too: If you're a beginner, using more muscles means getting fatigued sooner -- which will result in burning fewer calories. Try using a pre-programmed workout that includes variations in speed and intensity. Or vary those factors yourself during your workout. There are so many things you can do to make it more interesting. Personally, I would stick with options like Walmart or purchase directly from the Nutrisystem website, just to ensure that what you are buying is authentic and fresh.

With a baseline price starting under. The cost can go up, however, depending on which kit you go with:. In addition to the 5-day kits, Walmart also offers a broad selection of other Nutrisystem products. These include things like their Turbo and NutriCrish Shakes, individual meal options breakfast, lunch, dinner , bars, and desserts.

So, in a sense, they also have an a-la-carte menu to choose from. As far as I know, the Nutrisystem kits and other menu items have to be purchased online, but you can have them shipped directly to your home or to your nearest Walmart store. Obviously, these kits are going to include more food than the 5-day versions, but just like the other kits, you get full access to the Nutrisystem counseling program. To buy these kits you can buy a special card from Walmart, and then they can be redeemed on the official Nutrisystem website.
