lab day 7: human senses

Today we have been doing some experients to stimulate our sensory system

VISION

• colourblindness test: if you can't  distinguish the orange circle and the red star from the green background, then you are colourblindness
  

•  optical illusions: sometimes the brain fills the missing info to compensate the missing data coming from the blind spot

SMELL ON TASTE

•  prepare your partner 3 glasses with 3 different juices
• pintch ypur nose and close your eyes and see if you can guess what juice are you drinking!

 TOUCH

• unfold a papel clip and refold it so the two tips are toghether
• while your partner closes the eyes place one or two tips in both parts of the hand
• ask him to say how many tips does he feels
