Crayola Color Wonder???

[pattyT]

Anyone know how these markers and fingerpaints work? (except for the delay - dd 14 months doesnt like the fingerpaints cuz of that!)
my kids love them - and so do I (no mess!!!)
I just don't get how they work...

I don't know either but they sure are great!!! You might be able to find the info on the Crayola website.

I love this stuff too but watch out for it on certain types of woods ( read dining room tables!) my moms oak table still has some marks on it from when this first came out.


and I have no idea how it works either LOL

I found this for you.


"This is caused by the interaction between two complementary
phenol-formaldahyde compounds, similar to the technology that is used on
carbonless copy paper (those two-part receipts that are used for credit card
sales). The actual ingredients are a proprietary secret, but the general
idea is that the paper is coated with one chemical, and the marker tip
contains the other. When they mix they change color (kinda like
phenolphthalien, a solution of which is normally clear but which turns color
in the presence of a base or acid). The chemical in the marker tip is
nonreactive with most other surfaces, which is why you can't use the markers
to draw on walls or clothing (or people). The potential still exists for
the markers to draw in color, but the chemical activator isn't present to
make it happen.

Thanks!
It sorta makes sence - except the reference to carbon paper leaves me because carbon papers don't change colors on demand
Must be that secret ingredient -
thanks for the heads up on the wood ting too as we are going to buy all new furniture in the next 6 months and I will make sure they don't use it on that!!!
