Introduction: Tornado Bottles
Get in a spin making the amazing Tornado in a Bottle!
Amaze your family and friends by having a portable tornado! And you recycle two old bottles!!!
Just follow these instructions.
Step 1: You Will Need
You will need:
//2 Litre bottles x2
//Gaffer tape/duct tape
//Washing up liquid
Step 2: Where to Start
What do do:
Fill one of the 2 litre bottles just over half full of water and pour one drop of washing up liquid into the water.
Now pick up the empty 2-litre bottle and join the necks of the two bottles together.
You need to make the join between the two bottles very strong, so wrap A LOT of gaffer tape / duct tape around the neck.
Step 3: To Create the 'tornado'
Turn over the bottle with water in very quickly and 'waggle' the bottle (you need to practise this technique!) so the water is swirling around into the empty bottle below.
Hey Presto! Your very own tornado!
Step 4: The Science of It!
When the water is spinning down the neck of the two bottles, the air in the bottle rushes up to meet the water.
This creates a vortex.
Real tornados are created when a column of warm air rises and air rushes in at ground level and it begins to spin. If the storm gathers energy, a twisting, spinning funnel then develops.
Tornados are the fastest winds on earth reaching up to 300 miles per hour!
