Color Mixing Science

This is one of MD's favorite activities.  I put baking soda and some salt on a cookie sheet, fill two bottles for ketchup and mustard with vinegar and food coloring (one red and one yellow), and let him squirt the colored vinegar onto the cookie sheet. 

He loves to see the fizzle action as he pours the vinegar and he likes the color mixing as he makes "orange" from the red and yellow colored vinegar.  He actaully calls this art and when he's done squeezing the bottles he tells me we need to let it dry on the counter like his painting and other art projects :)

  1. Tremendo experimento de Ciencia! Si no me equivoco Vinagre y Bicarbonato de Sodio es una reaccion acido/base. Por eso burbujea. Me encanta.
