  4. 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

  9. 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
