Question

Why does it say "shake well" on ketchup bottles, but not ketchup packets?

Answer 1

In the bottle, to help the sauce come easier...

Answer 2

Ketchup bottles have those liquid water thingy while the small packet has a small amount of it.

Answer 3

Because in the bottles there is a larger amount of space so the oils can separate and have to be shaken in order to re-mix them, however in ketchup packets, they are smaller, and completely full, so there is nowhere for the oils to separate to!!!!!!!

Answer 4

in bottles, since they're bigger than the packet, all the flavor will go to the bottom, and that's why sometimes the ketchup comes out like liquid when not shaken, but since the packet is so small, there really isn't anywhere for the ketchup to separate and stuff...

Answer 5

air

Answer 6

Answer 7

More air in the bottle.

Answer 9

Because the packets could burst and it will go everywhere, unlike bottles.
