Experiment that can be done at home to proof that there is iron in cornflakes.
Your parents probably tolled you to eat up your morning cornflakes, because they contain iron to make you strong.
Here is the proof that cornflakes really contain iron:
- A permanent magnet (you may have one on your fridge door)
- A blender
- A transparent plastic sack, that can be sealed tightly
Put the cornflakes in a blender and add some water. Blend it to a slurry. Put this slurry in the transparent plastic sack and seal it well tight. Make sure the sack doesn’t leak.
Put the sack on a table and rub it with the magnet. One will see that little black particles are attracted to the magnet. This is the proof that there is really iron in cornflakes! This is the same iron as in a bike or a nail! So, don’t eat too much serials when your going to the airport; the metal detector might go off!
Maybe you want this to try with spinach, then you will also see that Popeye was right .
Second fun experiment:
- the permanent magnet
- two – five metal paperclips
Rub one of the paperclips along the magnet. Then try to pick up the other paperclip with rubbed paperclip. You will see that that the rubbed paperclip has become also a magnet! Then the next paperclip will also be magnetized and so on. How long can you make the chain?
