Make black snake with and without fireworks

A black snake, also refer to as  sugar snake, is a classic food based science experiment. We can do at our own place simply using the house hold chemicals, such as backing soda and sugar mixture and a fuel to ignite the reaction. There are two versions for this experiment that is with or without using fire

1. BLACK SNAKE WITH FIRE.

Reagents and equipment

• Backing soda (10g)
• Sugar 40gm
• Fuel
• Ceramic bowl
• Sand
• lighter fluid or alcohol

Procedure

 Step 1 : Add sand to a ceramic bowl, and soak the sand with a lighter fluid or alcohol.

 Step 2 : Mix the backing soda and sugar together, then it is added to the socked sand surface.

Step 3 : Now, just light it with a long stick match or lighter.

Process

When the backing soda gets hot, it makes carbon-dioxide gas a lack of oxygen in the sugar from the burning creates carbonate and water vapor. The pressure from carbon-dioxide gas pushes carbonate from the burning sugar out, producing the black fire snake, which should continue growing for 20 minutes

Note: Keep some water near by as a safety precaution in case you need to extinguish the fire
            Don't eat the resulting snake and touch it once it has cooled completely. 

2. BLACK SNAKE WITHOUT FIRE

Reagents and equipment

• Sugar
• Concentrated sulfuric acid
• Beaker (50 ml)

Procedure

 Step 1 : Take sugar in 2/3 of a beaker

 Step 2 : Add 10-50 ml concentrated sulfuric acid  

Process

Sulfuric acid as greater dehydrating and oxidizing ability, it causes the breakdown and carbonation of sugar when the mixture gets hot water vapor and carbon dioxide are released . This result to the products of the breakdown of sugar being pushed out of the glass. As soon as they make contact with air the cool and harder
