"The physics of that is pretty interesting and easy to understand," says Licini who, along with first-year physics major Allen Zijun Yuan, wrote a paper on the phenomenon that was recently published in The Physics Teacher. In the paper, they find the center-of-mass of a shampoo bottle, discuss its stability on a tilted surface, and demonstrate its sensitivity to impacts using a simple experiment involving a tennis ball and a protractor.

They write: "An object placed on a tilted surface and released will tip over if the horizontal position of the center of mass lies outside the geometric outline of the base of the object. This means that an object with a low center of mass will be stable for larger incline angles. Students are often surprised to see that the altitude of the center of mass of a shampoo bottle is a nonlinear function of the fraction occupied by the contents. This can, however, be seen in a straightforward manner by recognizing that for a plastic bottle, the mass of the liquid contents is usually far greater than the mass of the bottle. When the bottle is either completely full or completely empty, the center of mass must be approximately at the geometric center of the bottle, but the center of mass gets significantly lower in altitude for small liquid levels in between those two extremes."

Yuan developed a demonstration to show the effect of impact and, it turns out, even more extreme than just looking at angle.

A five-minute video of this demonstration is available can be viewed here. The experiment that uses a tennis ball, protractor and shampoo bottles with varying degrees of fullness to show the effects of impact starts at 2:40.

As Licini explains in the video, using a full bottle of shampoo: "So, what we have here is a tennis ball mounted on a string that can draw back to different angles. You put a protractor over here to measure that launch angle. And watch what happens as it impacts this shampoo bottle. So, you can see that for an angle of ten degrees, nothing happens. For an angle of 15 degrees, the bottle's still stable. It takes an angle of about 23 degrees in order to give this bottle enough rotational energy or angular momentum, in order to raise the center of mass above the stability point, and topple [the bottle]."

Conducting the experiment with a shampoo bottle that is 30 percent full, Licini says: "When we have our bottle with the lowest center of mass about filled to 30 percent, again it's still fairly stable. At five degrees, it bounces off no problem. At ten degrees, there's impact but still it rocks and then comes back to stability. That's because the center of mass is low. It takes an angle of about thirteen degrees in order to finally knock that bottle over."

Then, finally, using the empty shampoo bottle, Licini explains: "But the empty bottle is much more annoying than all that. Because the mass is so light, that means it's going to have a large response to impact. And, because the center of mass is so high [above the base], it's going to topple over easily. So, in this case, it only takes an angle of about three degrees in order to knock that bottle over. So, much less stable than any of the other configurations."

"We constructed a demonstration to produce impacts from a pendulum bob," write the authors. "A tennis ball of mass 57.7 g striking the bottle at an altitude of 13.7 cm turned out to be a good match of mechanical impedance and center of percussion. A string was tied to the tennis ball so its center would travel in an arc of radius 37 cm, and a protractor was mounted to determine the release angle of the pendulum, with 0° indicating the point of impact when the string was vertical ...The launch angles required for the impact to tip the bottle could be determined to ±0.5°and were approximately 20.5° for a full bottle, 12.0° for the maximum stability level, and only 3.0° for the completely empty bottle. The initial potential energy of the tennis ball at these angles is given by mgl[1 ? cos(?)] and yields corresponding values of 13.2 mJ, 4.6 mJ, and 0.3 mJ, illustrating the drastic decrease of energy required to tip the empty bottle."

Reuse Shampoo Bottle or Other Plastic Bottles To Make Holders

Don' toss out that empty shampoo bottle! You can use it or other empty plastic bottles to make handy holders and vases to use around the house!

Reuse Shampoo Bottle or Other Plastic
Bottles To Make Holders

What do you do with your shampoo, conditioner, lotion and other plastic bottles after they are empty? Did you know that a shampoo bottle will make for some really handy useful vases and containers to hold things?

Don' toss out that empty shampoo bottle! You can use it or other empty plastic bottles to make handy holders and vases to use around the house!

They work great to hang on the fridge to keep a pen and paper handy. They are also great in the bathroom on the mirror to hold a toothbrush and other items when you have limited counter space. Oh, they are also great in the shower to hold razors. Just be sure if using near water you use water resistant command strips.

So grab your empty shampoo bottle and I will show you how easy it is to make these!

Supplies Needed:

  • 1 Plastic Bottle (the flat sided ones work best)
  • Utility Knife
  • Scissors
  • Comand Hook
  • Marker

The first thing you need to do is wash the bottle really well. Then remove and stickers, labels or even ink. If you find you can’t wash it off easy, try using natural glue remover.

After you have the bottle clean, draw the outline of the shape you want. You want to make sure you leave the one part that is higher than the other.

Using the utility knife start cutting on your line. After you have started the cutting you may find it easier to finish using the scissors. Or even use them to just make sure you have smooth even edges.

Next thing you need to do is cut a small hole on that longer back piece that you left. This will be the hole to hang it on the hook from.

Now simply place the command hook where you want to hang your vase/container from. Then hook it to the hook using that hole you made.
