Volcanic Lava

Our experiment today was called 'Volcanic Lava.'
To do this experiment at home you will need:
play dough
film canister
red and yellow food colouring
vinegar
baking soda
liquid dish washing soap
2 small plastic cups
 Mould the play dough around the film canister to make the shape of a volcano.
Collect your equipment.
  Place 2 teaspoons of baking soda in the film canister.
Add 1 teaspoon of liquid dish washing soap in the canister. 
Use the eye dropper to drop in 5 drops of food colouring.
On your marks, get set, go!
Tip in 1/2 cup of vinegar.

Does the temperature of the vinegar affect how fast the volcano erupts?
Does the shape of the volcano affect the direction of the lava flow?
What can be added to the lava to slow it down?
