Recently James decided to undertake a science experiment to see if he could make a raw egg bounce! Can you research the science behind his idea and find out why it might work??
Last
weekend I decided to do an experiment. My Sister had already done this
experiment so I thought I’d give it a crack!
I
put vinegar in a cup, and then I added a normal egg straight out of the fridge
and put it in the same cup. I left the egg overnight and in the morning I hoped
that the shell of the egg would become rubbery and turn bouncy.
The
next morning I woke up to a big surprise the egg was bouncy and soft as I
wished it do. I took it to school to
test it Mrs Stevens said to drop the egg
out of the class room window.
Now
this is where I got really nervous. The class were waiting below and began the
countdown: “5 4 3 2 1”.
I dropped the egg – splat went
the egg! I think that the egg shell fell off because the vinegar dissolves all
the shell. I was really amazed that the
egg looked like it had been boiled even though I didn’t boil it so I think that my egg experiment was
an average success and I’m going to try it
again but this time I’m going to leave it in the cup for a longer time - not
just for one night.
