Show your friends and family this fun, almost impossible magical math trick.
Start by, Laying out 5 straws, candles, or pencils. Now layout 6 more underneath it, as shown in the diagram.
Show your friends the straws and tell them that 5 and 6 make 9.
Give them a few minutes to figure out how that is a possibility.
When they give up, move the 5 straws as shown in the diagram.
