Oh, Frog march, thanks for the cool reply. It means that tool box will fall on the head with a soft touch, just like when teacher appreaciate his student by touching his head softly.

But I think due to air pressure and heat that sandwiches will be baked too much and hence it will not be in the condition "cracked by the jaws", then one has to "refer to the dentist". And the onion will go out in the space just like a "golf ball" or one can say tennis ball, so where that ball will fall in which court !!
