EXPERIMENT

EXPERIMENT

I would like to make ice from this experiment on salt and ice.



【Preparation thing 】
・Salt (500g) ・ice (1 kg) ・rubber band ・bag ・straw (spoon may be used) ・juice



First, ice is put into a bag.



Second, juice is put into another bag.
And a mouth in a bag is firmly bound with a rubber band.


(Appearance in a bag which put in juice)



Salt is put into the bag into which ice was put.



And ice and salt are stirred well.



If you think that salt was mixed with ice, the bag containing juice will be put in it.



It shakes slowly in 5 minutes for 10 minutes.



It is completion when you think that it became to some extent hard.



Since delicacy changes with juice Be careful.



If it does only on ice without putting in salt incidentally.



Since it does not solidify in this way, please do not forget to put in salt.

This result shows that salt causes ice and an endoergic reaction
and has the character to lower a surrounding temperature.
