How To Make A Vinegar Volcano! - Science Fair Projects


Things You Will Need

In order to make your own vinegar volcano, you will need -
  1. A large sheet of card.
  2. A pair of scissors.
  3. Some tape.
  4. A small funnel.
  5. Small plastic bottles (2 Nos.)
  6. Vinegar
  7. Food coloring
  8. Bicarbonate of soda
  9. Washing liquid
  10. A large plate
  11. One pencil.
  12. A tablespoon
  13. One teaspoon.

Step 1

Draw a shape as shown below on a large sheet of card. Be sure that the shape is big enough such that it fits around the bottle.

Step 2

Cut the shape out from the large sheet of paper and bend it into a cone shape. Using the tape, you can make sure that the shape stays as it is.

Step 3

Fill one of the bottles one-third with vinegar. You can use the funnel to fill the vinegar into the bottle. After that, add few drops of food coloring and one tablespoon of washing liquid.

Step 4

Keep the second bottle on top of a plate. Into this, add around 3 tablespoons of bicarbonate of soda using the funnel. Set the cone shape on top of this bottle. While placing the cone shape, make sure that the opening of the cone shape is on level with the opening of the bottle.

Step 5

Using the funnel, drop in the vinegar and washing liquid mixture into the second bottle. Try removing the funnel. What do you see? Your own bubbling vinegar volcano !

Baking Soda and Vinegar Erupting - Vinegar Volcano Experiment

The Science Behind This Particular Vinegar Volcano

The food coloring is added in order to create a unique coloring for the volcano lava. You can always use brown coloring but you can even try experimenting with different colors.
The bicarbonate of soda and vinegar mix together to form carbon dioxide gas. This is what makes the mixture foam and expand out from the bottle.

Make a Rocket

Rockets are fascinating!  They soar into the sky and help us know many secrets. Are you fascinated by rockets? If your answer is yes, you would be interested in this activity. The rockets that you can make safely will not go very far, perhaps much less then the rockets we enjoy on the Deepawali day. But then you will agree, the fun and excitement to make your own rocket has a totally different dimension.  The basic principle of rocketry is Newton's Third Law of Motion, that is, "For every action there is an equal an opposite reaction".  A big rocket uses chemicals to release an intense stream of gas out its tail end that propels it upwards.  A fuel is used in a rocket to produce this gas through some chemical reaction. The rocket fuel is sometimes liquid, and sometimes solid.  But, in all cases, a gas is ejected from the tail of the rocket. The first kind of rocket that we can make is propelled by a very safe gas - carbon dioxide.  The ...

Make a Periscope

Are you familiar with the word "submarine"? A submarine is a kind of boat that moves underwater. Submarines are common crafts for the Naval forces of any country. But, while moving underwater, submarines need to know where they are with respect to other objects on the surface of water. The device they use to do this is called a periscope.  Periscopes are optical instruments that can afford submariners a limited though vital visual picture outside their windowless hull. Traditionally, periscopes offered the submerged submarine its only glimpse of the outside world. Classic English war movies have also made them the submarine's most familiar feature.  For most of us, who are unlikely to come across submarines in real life, a periscope can make it possible to see round corners and over the heads of crowds during processions or at sporting occasions. In a periscope, two mirrors are arranged at 45 degrees to each other. One mirror captures the rays of light from t...
