Thing #9 online image generators

To generate these signs I used the custom sign generator tab and chose the warning sign generator website.  This site was extremely easy to use,  it was just a matter of click this and chick that and walla.  I chose to display two of these signs which I thought would be humorous to place in a chemistry classes setting.
 First one would be posted in a classroom and the second one in a laboratory setting :).
