You probably don't already know this tidbit, but it is possible for a grown woman to stick her arm into a 9536 and reach the bottom to clean it. However, it does create this awesome suction effect when she tries to pull her arm out of the vase. I wouldn't advise that you try this at home, trust me, I am telling the truth. For a fleeting moment I thought this monster was permanently attached at my elbow. I am happy to say we both survived the ordeal intact.
