Has it been a while since you’ve seen some of your family members?
Break the ice with this touch illusion.
Place your palm against another person’s palm.
Have the person rub the sides of both of the index fingers (that’s the pointer finger) with their other index finger and thumb.
As they rub up and down, they will probably shiver.
Try it yourself. Did it feel like your finger was very fat or that it had a “dead” feeling?
Can you make this work with only the tips of the index fingers touching? What happens if you try the trick with a person with a hand larger than yours? Or smaller than yours? Vary the ages of people, too.
