Sugar
Small ceramic plate or bowl - can use a tuna tin
Small cup
Measuring spoons
Lighter fluid
Long lighter or matches

Bucket of water or hose

Instructions

Prep Work
This experiment requires dry sand. Your sand might be damp if you get it from somewhere that is in contact with the ground, like a sandbox. If needed, spread your sand out on a baking tray and place it in direct sunlight or in the oven until it is completely dry.
Only do this experiment with adult supervision, in a location where it is safe to have a small fire. Have a fire extinguisher accessible for emergencies.

Instructions
1. Fill your plate or bowl with sand.
2. Soak the sand in lighter fluid.
3. Mix 1 tbsp baking soda with 4 tbsp sugar.
4. Pour the sugar/baking soda mixture into a pile on top of the sand.
5. Use matches or a lighter to ignite the lighter fluid.
6. Watch closely, and be patient. The reaction may be slow to start.
7. Wait at least 10 minutes after the flames stop for your fire snake to cool. Have an adult make sure it is no longer hot, then you can touch it.

Cleanup
Douse your fire snake and sand in water to make sure there are no remaining flames, then it is safe to dispose of all the materials in the trash.
