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.

A fun activity that can be done with children of any age.

2 straws

string

sticky tape/masking tape

Scissors

And plenty of Space

Measure out two long pieces of string, make sure they are of equal lengths. Thread on a straw on each piece. We taped our string from one end of the room to the other but you can use be more precise in your measurements and use 2 chairs measuring out a specific length.

Blow up the balloons and twist the ends and attach a paper clip to stop the air from escaping. Attach the balloons to the straws by using some sticky tape.

Carefully remove the paper clips and let the balloons go together. Watch how far they travel.

Get ready for take off!

By using different shaped and sized balloons, you will be able to rate what balloons travels the furthest and quickest. The air inside the balloon in under pressure causing the balloon to expel it and pushing the balloon the other way, like a rocket!

Cornflour Slime

The boys have been making slime at home today, experimenting with the touch and playing and having fun!

This is a great activity to do with children of all ages, I doubt that there is any child or adult that will enjoy playing with the slime.

What you will need

Box of cornflour

Water in a jug

Food colouring of your choice
We used green to look like slime

Plastic tray or a plastic tub

Tablespoon

Instructions

Put your cornflour into a tray

Add some food colouring to the water

Gently and slowly add the coloured water to the tray of cornflour an mix with a spoon, add small amounts at a time as you don’t want the mixture to be too watery. Once all combined get your hands in!

Now your ready to play!

Is the mixture a solid or a liquid?
The boys say both.

Roll the cornflour slime into a ball – it becomes a solid mass, once you stop it becomes slime
Try Tapping, punching, rolling it, running your fingers through it and letting your hand sink in it
What happens?

The boys play with this for hours and never seem to bore of it, it can become messy but once it is dry the slime can be easily swept off of the floor and wiped away from sides. It is easy to wash off of your hands and clothes and is non-toxic, so it makes fabulous play for the younger ones. It is non sticky and can be stored away in the tub in the fridge ready to be played with the next day.
