Safety
* Put protective eyewear on.
* Conduct the experiment on the tray.
* Keep a bowl of water nearby during the experiment.
* Place the stove on the cork hot pot stand. Do not touch the stove after the experiment; wait until it gets cold.
Disposal
Dispose of solid waste together with household garbage.
Step-by-step instructions
1. Take the solid fuel stove from the Starter kit. Place a piece of aluminum foil onto the stove. Caution! Use a cork hot pad to protect the tabletop.
2. Place the plastic ring in the center of the foil.
3. Pour out all the solid fuel inside the ring (2.5 g).
4. Take the press mold and push it down into the ring to make a crater with the solid fuel. Now, carefully remove the press mold.
5. Remove the plastic ring while slightly tapping onto it.
6. Pour in two level measuring spoons of sugar (2 g) into a vial with 0.5 g of sodium bicarbonate (NaHCO₃) and close it with a cap.
7. Shake the vial for 10 seconds to mix sugar and sodium bicarbonate.
8. Now, pour out the mixture of sodium bicarbonate and sugar into the crater you made in solid fuel.
9. Ignite the solid fuel – and very soon, it will grow into a black “snake”!
