In the old days, people often put peanut butter together with jelly on
some bread. Back then this was safe. But today, this is a very
dangerous thing to do. The chemicals used in manufacturing both the
peanut butter and the jelly are corrosive. By themselves, there is no
problem. However, when these ingredients are combined, the create a
dangerous substance. Several persons have been seriously injured when
their PB&J sandwiches sat for several hours, and exploded due to the
chemical reaction of this dangerous combination. Unfortunately, most
of the injuries have been to children. One child opened his lunch
bag, and pulled out his PB&J sandwich. As soon as it hit the air, it
caused a violent explosion. The child, as well as several other
children at the same lunch table were taken to the hospital and
treated for severe burns and even broken bones as a result of the
blast.

Never mix Peanut Butter with Jelly for any reason.......
