October is always a fabulous month. It is a month where Autumn is taking root and the food is ready to harvest.

Foaming Pumpkin

Which is why we have included the foaming ‘pumpkin’ in this months box for you to enjoy. Now this experiment will take some adult supervision and time. The first step is to carve your squash. There are some really good images out there so google pumpkin carvings and try to one of these designs. Squashes in our opinion are easier to carve, not only because they are smaller but they have less seeds to remove. Once it has been prepared. It is time to do the chemical reaction.

This reaction is known as Elephants Toothpaste. It is great and we have used it to adapt into so many creations. This time it will created a forming pumpkin. Take the yeast packet and pour it into the bowl. Add water to activate the yeast and stir until mixed into a creamy liquid. There needs to be no lumps and it needs to be of a runny consistency. After you have done this set to one side. Put the square container into the squash. If it doesn’t fit, carve the squash a little more so it fits in. Place the Hydrogen Peroxide into the square container and add some bubble mixture. Then add the activated yeast to the mixture in the squash and place the lid back on. You will see the pumpkin start to form and should come out of the carving and may lift the lid. The bubbles are safe to touch. They will be warm as the reaction is a thematic reaction that means it gives off heat as the reaction takes place and the oxygen is separated from the hydrogen.  The oxygen is captured in the bubbles and so makes the foam.

sweet rainbow potion bag foaming squash

Skittle rainbow.

This is a fun and easy experiment that is an instant hit with children. Ask them to place the sweets in a circle around a plate. This magical experiment is great, the colours from the coated sweets dissolve into the water and stretches across the plate.

Magic pepper

This one also requires a plate and some water. This one requires you to sprinkle the pepper onto of the water. Take one cotton bub, dip it into some bubble mixture and touch the pepper. The pepper will separate across the plate as the bubble mixture changes the water tension.

Cabbage Water

The cabbage you have will need to be boiled for several minutes then cooled before use. Cabbage water is a PH indicator. So the liquid acts like a magical liquid that changes colour depending on what is it added to. Using your pipette. Add the liquid to the range of liquids that have been provided. You can also try various liquids in the household such as toothpaste, fruit juices or soya sauces to see what the the liquid does to them and where they appear on the PH scale. Try mixing the liquids together to see what happens and what colour you end up with. Could you neutralise the liquids and produce a yellow?

Magic Plastic Bag

This is another experiment that needs water. Fill the bag with water and seal the bag. The bag is made of plastic. Plastics are a polymer their molecules are like links which is why they are so modifiable. Hold the bag with one hand and puncture the bag, continue to go all the way through using one movement until the pencil comes out the other way. The water will remain within the bag as the bag forms a vacuum around the pencils.
