We Try Food Experiments Without Instructions

Ingredients

• 200 g Chocolate (semi‑sweet or milk) (break into small chunks; use good quality chocolate for smooth melt)
• 100 g Dry Ice (solid CO₂) (handle with gloves; keep in insulated container until use)
• 1 tbsp Corn Starch (Maizena) (optional; can be sprinkled on dry ice to observe extra fizz)
• 1 piece Lollipop (for dipping) (use as a fun dip handle; any sturdy candy stick works)
• 1 pair Gloves (heat‑resistant) (protect hands from dry‑ice burns; disposable kitchen gloves work)
• 250 ml Milk (whole or 2%) (use a shallow plate for best visual effect)
• 1 tsp Dish Soap (liquid) (any clear, low‑scent liquid soap; a drop is enough)
• 3 drops Food Coloring (red, blue, yellow) (use one drop of each color; can substitute with natural food dyes)
• 1 piece Bubba Straw (wide‑mouth straw) (optional; can be used to blow gently on milk for extra motion)
• 2 pieces Chopsticks (for handling dry ice and stirring chocolate)
• 1 piece Plate (shallow) (for the milk‑soap‑color experiment)

Instructions

1. Safety First

   Put on the heat‑resistant gloves and ensure you are working in a well‑ventilated area. Keep dry ice away from children and pets.

   Time: PT2M

2. Prepare Chocolate

   Break the chocolate into small chunks and place them in a mixing bowl.

   Time: PT1M

3. Add Dry Ice to Chocolate

   Using chopsticks, carefully add a handful of dry‑ice pieces to the chocolate. Stir gently; you will see vigorous bubbling as the CO₂ sublimates.

   Time: PT2M

4. Optional Corn Starch Sprinkle

   Sprinkle 1 tbsp of corn starch over the dry‑ice‑chocolate mixture and watch the extra fizz created by the starch particles.

   Time: PT1M

5. Taste Test (Optional)

   Use the lollipop as a dip handle and gently touch the chocolate‑dry‑ice mixture. Observe the crackling, but do not swallow any dry‑ice fragments.

   Time: PT1M

6. Set Up Milk Experiment

   Pour 250 ml of milk onto the shallow plate, spreading it into an even thin layer.

   Time: PT1M

7. Add Dish Soap

   Drop 1 tsp of liquid dish soap into the center of the milk. The soap will begin to break the surface tension.

   Time: PT1M

8. Add Food Coloring

   Add one drop each of red, blue, and yellow food coloring around the soap drop. Watch the colors swirl outward.

   Time: PT2M

9. Optional Air Motion

   If desired, gently blow through the Bubba straw across the milk surface to create additional movement.

   Time: PT1M

10. Cleanup

    Allow any remaining dry ice to fully sublimate before disposing of it in a well‑ventilated area. Wash all utensils with warm, soapy water.

    Time: PT5M
