Pouring Vinegar onto baking soda

Coolest thing ever!  Pictures do not do this justice.  Just be sure to have a lot of baking soda and vinegar on hand.  They will want to do it again and again!  


Round 500  LOL  LOL


This will also work with glow powder.  However, it’s much more expensive and harder to find.  We just happened to have some on hand.  Yes, this is stuff we have on hand at our house.  LOL

“This is so cool, Mommy”

“It’s all gone???”
We also did this with elephant toothpaste.  For our elephant toothpaste post click HERE
To make the “toothpaste” glow, mix glow water or glow powder with the peroxide.  
I wish I had better pictures of this but I was to busy playing!  I will update when we do it again.

    I bought a black light at Walmart yesterday for $11. They also have black light bulbs you can put in a lamp.

    I am wondering how you keep your glow water from turning gross? Or do you make it and use it immediately, then throw it out? I could not get the back off the highlighter so I taped it inside my tub tip down and left it overnight.


  2. Highlighter does not stain the tub, or your child. As long as you buy non-toxic highlighter, I do believe it is safe. We have explored a lot with glow water, and have had nothing but fun. You can make an array of glow water colors too :)

    I believe tonic (mineral) water glows like that too…. something to do with the minerals in it….. it may not be as bright or dilutable, but I know it glows. I love all these cool kids ideas! :)

    Just highlighter in water will glow under a black light.. We also use them to draw things on stuff an our selves for a haunted house… After you shower you won’t see the highlighter on your skin but it will still show under the black light for a while
