Super bubble blower
30 minutesWhat’s the difference between a bubble blower and a super bubble blower? Do you want to blow a lot of bubbles? Or just very big ones? Or do you want bubbles that last for a long time? Find out how to make your own super bubble blower!
Requirements
Steps
Put a tablespoon of washing-up liquid into the drinking glass. Pour water into the glass until it is three-quarters full. Stir the water to mix it with the washing-up liquid.
Cut off about 20 cm of the iron wire, and fold it double. Twist it to create a double wire.
Shape that double wire into a circle with a diameter of about 2 cm. Twist the ends around each other to create a handle. You’ve just made your own bubble-blowing loop!
Dip the loop into the liquid in the glass. See if you can blow some bubbles. How many can you blow? How big are they? How long do they last before they burst?
Add a scoop of sugar to the bubble-blowing mixture. Stir the mixture thoroughly, until the sugar has completely dissolved. Try blowing bubbles again.
What happens now? Bigger bubbles? More bubbles? Longer-lasting bubbles?
There is no end to the number of things you can investigate. This is because there are lots of things you can change (variables). For instance, you can:
– use different brands of washing-up liquid
– put more or less washing-up liquid (two spoonfuls or just half a spoonful) into the glass
– add more or less sugar
– add no sugar, but try glycerine instead
Make different mixtures and find out which recipe works best in your super bubble blower.
Do you want to make giant bubbles? Then make a bucketful of the same mixture and add glycerine instead of sugar. Use two wooden rods and a piece of string to create a giant loop for making the bubbles.
Go outside and use the bubble loop to make the biggest bubbles you can.
