How do I acquire a picture of a rising tube of red mercury in Power Point?

[peterngoodwin]

I need to display a red tube of something like mercury (red liquid rising) like in a temperature tube but I'll insert my own numbers? Clip art does not have what I am looking for and I can't find photos of a red tube rising. Something where I might show a $2500 achievement and a $10,000 goal.
