  1. Balloon Popping Trick

    Balloon Popping Trick

    Can you pop a balloon without touching it?

    Yes you can! All you need to know is the balloon’s secret nemesis- the humble orange (or lemon)! That’s
    right— latex balloons have a major citrus allergy.

    What you need:
    ● Balloon
    ● Citrus fruit

    What to do:

    1. Blow up a latex balloon.

    2. Take a peel from a citrus fruit (orange or lemon will work) and squeeze it hard enough to spray the oil
    from the peel at the balloon.

    OR scratch the zest off or a lemon, making sure you get plenty of zesty oil on your finger (invisible to the
    naked eye) and pop your balloon in front of your friends with a single, light touch- your friends will be
    lost for words!

    3. You’ll see that exposure to the citrus oil immediately pops your latex balloon.

    Why is it so?

    Well, there is a chemical in citrus fruits called limonene, which is a hydrocarbon that is actually used in

  7. Ferocious Dino Competition

    It is time for our first competition of 2019, and we have a massive dino-sized, dino-themed pack of prizes up for grabs - see below for how to enter and a list of all the goodies on offer!

    How To Enter

    1. Firstly, think of your favourite dinosaur. Is it the terrifying T-Rex, the armoured Stegosaurus, the speedy Velociraptor or Australia's own Muttaburrasaurus?
    2. Next, create a drawing or painting or any other form of artwork of your dinosaur.
    3. Now, think of the features (also called 'adaptations') that your dinosaur has that enable it to survive. These might be things that help it to catch and eat its prey, or perhaps defend itself from predators. Choose three features and label them on or next to your artwork.
    4. Send your entry to us, by email (see below) or 'snail mail'. All entries must be with us by Friday, 19th April

    Send us your entry by email or snail mail.

  8. Hatch a Dinosaur out of an Ice Egg!

    Hatch a Dinosaur out of an Ice Egg!

    This activity is perfect for keeping young dinosaur enthusiasts cool on a hot day.


    You Need:

    Some small dinosaur figurines (or other animals that hatch out of eggs, such as lizards or birds)

    Some round balloons (not water balloons)


    Some toy tools, or other safe objects for breaking or melting ice


    What To Do:

    Stretch a balloon carefully around the figurine, taking extra care not to puncture it with any spikes or claws. (Water balloons are too thin and can break at this point).

    Place the opening of the balloon over the end of a tap. Turn the tap on gently and fill the balloon with enough water to surround the figurine.

    Seal the balloon and place it gently in the freezer overnight.

    When your ‘ice egg’ is completely frozen, use the scissors to remove the balloon.

    Place the egg in a tray with appropriate tools,  and invite your young dino-e

  9. Use Chemistry to Hatch a Dinosaur Egg!

    Use Chemistry to Hatch a Dinosaur Egg!

    Got a dinosaur enthusiast at your place? Make a dinosaur egg they can hatch with a chemical reaction!


    You Need:

    A packet of Sodium Bicarbonate (baking soda, from the supermarket)

    Some food colouring

    Mixing Bowl



    Small dinosaur figurines (or other animals that hatch out of eggs, such as lizards or birds)

    Baking tray with a sheet of baking paper or foil to line it

    Vinegar in a small cup or bowl

    Pipette (eye dropper) or small spoon


    What To Do:

    Pour the sodium bicarbonate into the mixing bowl.  Put on the gloves, then add a little water and a few drops of food colouring. Mix with a spoon or your hands to form a mouldable paste, adding more water if necessary.

    Take a handful of the paste and mould it into a small bowl that you can place a figurine inside. Place more paste on top of the figurine and mould into an egg shape, ma

  10. Candy Cane Chemistry

    Candy Cane Chemistry

    If you suck on a candy cane long enough, it will dissolve in your mouth. In this experiment you can observe the process up close, and also find out which liquid will dissolve a candy cane the fastest. It is easy to set up with household materials and substances (and a packet of candy canes), and a great opportunity for developing the science skills of hypothesising, observation, measurement, fair testing, comparison and analysis. It also a great way to use up your left over candy canes at Christmas!

    You Need

    • 6 candy canes, any plastic wrapping removed
    • 6 clear glasses or jars
    • A stopwatch
    • bar magnet
    • 6 different liquids such as cold water, hot water, salty water, water with food colouring, vinegar, oil, juice, milk etc.

    What To Do

    • Pour different liquids into each glass or jar, then label
