Halloween is a great excuse for turning your kitchen into a laboratory making icky stuff for kids – both big and small! Here are a few offerings for the upcoming 31 October festivities. If you haven’theard yet, Halloween is a celebration of all things magic, weird and downright frightening. In the northern hemisphere it is associated with the endo f summer, hence decorating with autumn harvest pumpkins –preferably carved.

SLIME: Science Bob’s recipe starts with 1/4 cup of glue (eg Elmer’s school glue / Aquadhere/ white craft glue / PVA glue) and 1/4 cup of water. Once these are mixed in a bowl, add some drops of your favourite food colouring. The last ingredient is 1/4 cup of liquid starch (eg Sta Flo) and adding this will see the mixture start to thicken. The more you play with this concoction, the easier it will become to hold. Store the slime in a plastic zip-lock bag and keep it away from carpet or hair.

Alternatively, Questacon suggest slowly adding water to a bowl of cornflour (not wheaten cornflour) until a thick slime forms. If you punch the slime forcefully with a fist, it will feel hard; however if you push only slowly it will instead feel wet and runny. Welcome to the world of non-Newtonian fluids.

GLOW IN THE DARK DRINK:

Science Bob also notes tonic water contains quinine which will glow in the presence of a black light. Make ice cubes of tonic water and then add them to a light coloured drink such as lemonade. The cubes will glow blue in the black light, and as the cubes melt the whole drink will come to glow.

FAKE BLOOD:

Mix 175g of cornflour with 75ml of water. Add 175ml of golden syrup or corn syrup. Lastly add teaspoons of red and green food colouring at around a 3 : 1 ratio as if you only use red, it will be too bright. To double check the colour, place some drops onto a piece of white cloth; but be warned that the food colouring can stain, including your hands. Using a kitchen blender can cut down on the mess.
