Create An Amazing Erupting Volcano

Joseph and I made this volcano the other day, it was fun and simple to do.

You will need:

A clear plastic bottle (we used a Highland spring bottle which was green but still see through)

Scissors

Plasticine

Tape

Paper

Felt tip pens

For the lava:

Baking Powder

Vinegar

Washing up Liquid

Red food colouring

Instructions:

Firstly you need to cut the bottle in half and discard the bottom half as you will only need the top part.

Secondly, cut the top part of the bottle off, about 1-2 cm will do, this will create the magma chamber. Turn the part that you have cut off and place it upside down into the bottle.

Next you need to seal the edge of the magma chamber with some tape and some plasticine (i used red so that it looked like lava)

Now you need to decorate the volcano! Cut out a collar of paper, so that it will fit inside of the bottle and colour it in so that it will look like an exploding volcano. Once done, push the collar up inside of the bottle.

Now for the fun bit!

To make the lava mix you will need to mix together 150ml vinegar, three tablespoons of washing up liquid and about 2 drops of food colouring

Spoon 2 teaspoons of baking powder into the magma chamber.

It can get quite messy for the next bit so i advice to either put the volcano onto a tray or take it outside!

Slowly pour the lava mixture into the magma chamber and now wait for the eruption to begin! It will firstly begin to bubble and then the lava will start to spill over the sides of the volcano.

The fun thing about this volcano is that it can be used again and again, just wash out the chamber ready for the next time.
