Never use empty food/water containers to store chemicals. Lots of kids die or are seriously injured from this mistake. We just had in article in our local paper about one such tragedy.

Also, remove the block with 20 knives from your kitchen counter. You need to make it a little harder for a home invader to find a huge knife. One of my wife's co-workers was nearly stabbed to death in her own home, by a home invader who used a knife from the kitchen butcher block.
