Watch the video of Sarah’s school science experience at STEM Academy Neisd in the video player above.
Are you looking for something fun to do at home that has a little science behind it? This carbon sugar snake is a great way to show chemical reactions.
Make sure you consult GMSA @ 9 on Wednesday when the meteorologist Ksat Sarah Spievey demonstrates and explains science behind it. To display, click on the video player above. Discover our Science web page with Sarah For more fun scientific experiences!
Here is what you will need
For snake sugar
-
Pie kit
-
Sand
-
Soda bicarbonate (1 teaspoon)
-
Powder sugar (4 teaspoons)
-
Bol to mix – Small
-
Lighter liquid – or ethanol
-
Lighter
For safety
-
Glasses
-
A hair tie (if you have long hair)
-
A nearby fire extinguisher
-
Adult supervision
Experience
-
Step 1: Pour the sand into a mound in the pie
-
Step 2: Make a divot at the top of the mound
-
Step 3: In a mixture bowl, mix 4 teaspoons of powdered sugar with 1 teaspoon of baking soda baking soda
-
Step 4: Dip the divot of the sand mound in a lighter liquid
-
Step 5: Pour the soda / sugar baking soda mixture
-
Step 6: Dimin and light the lighter liquid with the lighter
-
Step 7: Look at the black bubbles form. Wait 5-7 minutes and a longer carbon “snake” should form
To turn off: Cover the heat with another pie or turn off with water. Make sure the fire is completely off before throwing everything
Why it works
Sugar is made of carbon, hydrogen and oxygen. When burned, it produces carbon dioxide and water vapor. These gases raise the snake. When we add baking soda, more gas are created. Soda bicarbonate also prevents sugar from burning completely, the creation of black carbon – or charcoal. This is why the snake is black.
