SMMART SCIENCE: Fizzy Jack-o-Lantern Juice

This fun activity results in the production of Carbon Dioxide (CO2) in a fun fizzy drink.  We put a little Halloween twist on this one.

Ask your little haunt to use a black sharpie to draw a picture of a Jack-o-lantern on the front of a clear plastic cup.  Fill the cup with freshly squeezed orange juice to see the Jack-o-lantern appear. 

You can also use bottled lemon juice and a little food coloring to make the drink a nice orange.  (Here's a trick for Halloween:  It will look like orange, but taste like lemon)

Let your child use a spoon to add a little sugar to sweeten the drink to taste.

Now, let your child sprinkle a teeeeeeeny bit of baking soda over the drink.  You will see the reaction between the citrus acid and the baking soda begin to form fizz....or Carbon Dioxide bubbles.

NOW I DO MEAN TEEEEEEEENY bit of Baking Soda.  Let your child take a pinch of baking soda and sprinkle it on the top of the drink.  If you use too much, your drink will taste salty, so use just a little and taste the drink along the way as you add a bit more baking soda.

Enjoy your Jack-o-lantern juice!
