This is a Baking Soda (or Elephant's Toothpaste) Volcano for the Geology/Geography Studies

Design Contest, more specifically, the geology part. All you do is mix the ingredients for either one in the volcano and watch it go.

Baking Soda + Vinegar:

Ingredients:

• 1 ½ tbsp vinegar
• 3 drops of red food dye
• 1 ½ tbsp baking soda

Instructions:

1. Mix the vinegar and red food dye in the volcano. (A funnel may be useful)
2. Pour in the baking soda. (DON'T USE A FUNNEL; it can and will clog before all the baking soda comes out)
3. Watch the ‘lava’ come bubbling out.

Elephant's Toothpaste

Ingredients:

• 1 ½ tbsp hydrogen peroxide (The higher the concentration, the better)
• 3 drops of red food dye
• 1 squirt dish soap
• 1 tsp yeast

Instructions:

1. Mix the hydrogen peroxide with the red food dye, and dish soap. (A funnel may be useful)
2. Pour in the yeast. (DON'T USE A FUNNEL; it can and will clog before all the yeast comes out)
3. Watch the ‘lava’ come slowly bubbling out.

Notes:

• The Elephant's Toothpaste is very slow so be patient
• In the image attached for the Elephant's Toothpaste I forgot to add the red food dye and the dish soap so I had to add the red food dye afterword. This is why the color isn't very pronounced.
• AMS not required
• Any filament works, but I recommend using a dark brown filament so it looks more like a volcano. (For the images attached, I didn't have any, so I used a glow-in-the-dark filament.)
