Making GREEN with shaving cream!

Have a blast with this fun science-y activity of color mixing! It can be goopy messy so make sure yer kidlets appreciate a mess and wear not so special clothing. This is best done outside and is perfect for warm weather when you can bring out the hose or squirt bottles for clean up! If you can't do it outside, keep your mixing masterpieces in their plastic baggies and at the kitchen or play table or have your wee ones each use their own cookie sheet or tray. Shaving cream on its own is easily cleaned up. Shaving cream with color may stain so be sure you want to do all this before you start and remember, a little goes a long way! click here to see a larger version of the picture!

Clockwise from the top you too can scrumdilly-do it:

*Gather your supplies, unscented shaving cream (not gel), plastic sealable baggies and food color in yellow & blue or liquid watecolor in yellow & blue. (You can of course use any colors you like but here, we're making green! Oh and you can always find natural shaving cream like Tom's of Maine which has a minty scent. The regular stuff however can be found at your local dollar store.)

*Squirt some shaving cream into a baggie

*Add a drop or two of the two colors, one color on each side of the baggie so your kidlets can see the separate colors. Seal the baggie with as little air as possible so your kidlets can mush it all up.

*Agitate the baggies so the colors get mixed.

*See how there will be patches of yellow melding into the blue making green. Let your wee ones decide how many drops of each color they want. Use poster board or paper to create a graph. Let your wee ones math it out and explore!

*Sometimes the colors leak through, if your wee ones freak out wash hands and all will be well. Though blue is harder to get out than yellow!

*Snip a corner off the baggie and have your kidlets squeeze out the foamy goodness onto a clean washable surface or splat mat. (A plastic tablecloth will work fine and if your table is in need of a good cleaning shaving cream does a great job! Just ask any grade school teacher!)

*Mound it up in your hands for shaping fun. Show it off! Take pictures! Document! Go back to the charts and graphs and see what else your wee ones can write down.

*Most of all enjoy it and squish squish squish away! Once the food color is mixed in with the cream it shouldn't stain your wee one's hands or skin. It disolves easily with water and if they choose to make a painting with it the colors from the cream will stain their paper but the cream will eventually disolve.
