I Wonder . . .

During Munch and Crunch today, Zach in 1G found an interesting looking grape in his container. 

I posed the following question to 1G...

I wonder why the grape is half purple and half white....

Sam, Charlice and Praise thought it was because the grape was cold at the top.

Tanay, Sachin, Jocelyn, Zach and Ruby thought it might be because some of the juice had leaked out of it.

Tanay also thought it might be because half of it was left in some water.

If you can think of another reason why it is half purple and half white, add a comment!!
