Is Paper Vegetable Fit For Cooking?

'Six plus four is ten feet, Divided by two is five feet, I'm just above five feet, And can just walk thro' it.' So calculated a Math teacher, About to cross a flooding river, From the two foot-scales ashore, Fixed at both sides of the river. He not being a swimmer, Breathed his last forever. The average useless theory, A few may know this story, A book serves as a guide, As it can't always provide, For problems however little An all time solution practical. Can the paper drawn vegetable Be served for the dining table? Or will the wax made apple Cause our tongue tickle? A guide pole on the roadside, Can direct which way to ride, But it can't lead all the way, To the destination far away. A globe map in blue print, Gives a dot picture to hint, Or sketch out where we live But will it show the place alive? Should we not use our mind For any apt solution to find From the experience we gain, That is stored in the brain?
