Re: [Phys-l] viscous fluid

Shampoos are already *colored*...yellows, oranges, blues, etc. Suave is a popular brand and inexpensive; it comes in many different colors. Look for your favorite at Target or Walmart. It's so cheap you can buy a *class set*.

Liquid shampoo -- great idea!!

Is there any way to "color" these to contrast them against the clear
bottles I plan to put them in? I imagine food coloring won't mix very well.

I've used shampoo for a viscous drag on a ball dropping through a fluid
lab exercise. I'd estimate that we've had the same bottles of shampoo
in the lab for about 15 years and they worked fine last week. Liquid
hand soap is pretty viscous too.

I am looking for a similar fluid to that in an Ooze Tube -- the clear
cylinder with two halves connected by a small opening. When the tube
inverted, it takes a relatively long time for the colored fluid to
through the hole. I want to make a larger version of this using 1-L
bottles and a Tornado Tube connector.

I was planning to use honey. Does anyone have any experience with
Which brand honeys are most viscous? And do I have to worry about
crystallization? How about Karo syrup or molasses? I believe these
more easily than honey. Other viscous (and relatively clear) fluids?
