Liquid #2

I brought in a second mystery substance, but with a twist.  I altered this liquid slightly to throw the small scientists off of their game by adding food coloring (they're quite observant this year).  We did the same thing as before. I introduced it to the group and then they went off in their small groups to do some investigating.

With their words, I wonder if you can figure out what the substance is?  If you figure it out, don't tell!  

Here are some of their words:

Sight:  Blue, wet, juice, melted popsicle

Smell:  Lemon juice, gross, eww, The stuff you dye eggs with, room spray

Touch:  Wet, cold, gooey

Hearing:  Drain, ocean, water, nothing
