I was playing with an interactive “touch the screen” style trick for father’s day. This is the type of trick where someone starts by touching a object, then spells/counts several times eventually ending up on an object that you know.
The cool thing that I noticed is that if you spell the three words HAPPY FATHERS DAY the math works out for each word for to make it easy.
To do this you’ll start with five objects. These could simply be little pieces of paper that say things about dads, or whatever. You will line these up. For simplicity, I’m going to just use the numbers 1-5.
1 – 2 – 3 – 4 – 5
Touch the one on the left. You are going to move one space per letter. You can move left or right, but only to the one next to it, you can jump spaces or from end to end. Spell HAPPY, moving one space per letter and keep touching that one.
You’re not on the one or the five, so I’ll eliminate those.
2 – 3 – 4
Now you’ll spell FATHERS moving one space for each letter.
You’re not on the four, so I’ll take that one away.
2 – 3
Now spell DAY, moving one space per letter.
You’re on the 2!
That’s a very simple interactive math trick you can do for father’s day!
