====Summary====                   
{{$demo.summary}}



====Procedure====  
  - Refrigerate gelatin cups until cool and firm.  
  - Use a pushpin and small knife to create a hole in the bottom of the cup, just wide enough for the syringe tip.  
  - Fill a plastic syringe with pudding, yogurt, or chocolate sauce, removing excess air.  
  - Insert the syringe into the hole at the base of the cup.  
  - Put on goggles and remove the gelatin cup’s cover.  
  - Slowly inject the “magma” into the gelatin, observing as it intrudes and spreads inside.  
  - Continue injecting until the magma breaks through the surface, simulating a volcanic eruption.  
  - Remove the syringe, place the cup on a plate, and excavate with a spoon while eating, noting “sills,” “dikes,” and inclusions.

====Variations====
  * Use layered gelatin to simulate rock strata.  
  * Inject multiple types of sauces to model successive magma intrusions.  
  * Chill or warm the sauce to see how viscosity affects intrusion and eruption.



====Safety Precautions====
  * Wear goggles to protect eyes from splashes.  
  * Use caution with sharp tools when piercing the gelatin cup.  
  * Keep tools and utensils clean, since the activity ends with edible food.




====Questions to Consider====
  * How is the gelatin like country rock and the sauce like magma? (The gelatin is pre-existing rock, and the sauce represents molten rock intruding into it.)  
  * What geological features do the blobs, layers, and cracks of sauce represent? (Plutons, sills, dikes, xenoliths.)  
  * What changes when the “magma” erupts at the surface? (It transitions from magma to lava, modeling extrusive volcanism.)  
  * In what ways is this model similar to real volcanism, and in what ways is it different? (Similar in showing intrusion and eruption; different in scale, time, pressure, and material behavior.)
