3rd grade physics
Jakob's homework today was to show an adult (or more) a 'trick' from physics class this morning. And make us guess the result.
Here's how: Place a glass on a piece of paper. Then you fill it to the brim with water. And I mean to the brim! Then slowly 'insert' coins like this into the water, sideways (thin side down) into the glass. (This one's Danish, but never mind!)
How many coins can you put in before it spills?
I can say this much: I guessed 1, then 5 when laughed at... My hubby guessed 2. We were both wrong... Anyone?
I don't know that we even did physics at the age of 7 in my time...
Update: I'll post the answer in a comment, in case anyone else wishes to wager a guess. Wait, that won't work, will it? I'll post the answer under the comments of the previous post, then ;)
