In what brand of shampoo does a marble move the slowest?

It would be in the shampoo that has the greatest density.

Since this is not my area of expertise, I searched Google under the key words "shampoo density brand" to get this possible source:

I hope this helps. Thanks for asking.

the movement of one object around another is

determined by factors such as the density and viscosity of the fluid it is immersed in. In this case, the shampoo with the highest density will offer the most resistance to the movement of the marble, causing it to move the slowest.

To find out which brand of shampoo has the highest density, you can either look for specific information from reputable sources such as manufacturers' websites or product descriptions, or you can compare the densities of different shampoo brands by reading customer reviews or conducting experiments.

Searching online using keywords like "shampoo density" or "shampoo brand comparison" can help you find relevant information and comparisons between different shampoo brands. Additionally, checking online shopping platforms or review websites can provide insights into the features and characteristics of different shampoo brands, including their densities.

Remember that density is not the only factor affecting the movement of a marble in shampoo. Viscosity, which measures the thickness or resistance to flow of a fluid, is also important. So, considering both density and viscosity will give you a more accurate understanding of how the marble will move in different shampoos.
