David’s Ruler Trick

I haz made u all a video 🙂

Find out how old someone is/year they are born w/tape measure. We concentrated on the year-age but you can work backwards and find out the year they were born from their age!
for ex: if they were 84 they were born in 1927!

(yah i totally wonked out when i was trying to show my grandma’s year, but i’m sure you all get the point!)
