Portable child sink

A method of using an apparatus, the apparatus comprising:

• a base;
• a first reservoir disposed on the base and configured to hold a first fluid;
• a first vessel having a first volume equal to or greater than a volume of the first reservoir, wherein the first vessel is configured to be connected to the base;
• a first conduit configured to deliver the first fluid from the first reservoir to at least the first vessel;
• a first sensor;
• a first resistance measurement wire connected to the first conduit;
• a microprocessor;
• and
• a first pump;
• the method comprising:
• receiving a first signal from the first sensor indicative of whether an object is disposed proximate the first sensor;
• receiving a second signal from the first resistance measurement wire indicative of a resistance measurement of the first conduit, wherein a first threshold corresponds to a lack of the first fluid in the first conduit;
• determining that the first signal correlates with presence of the object proximate the first sensor;
• determining that the second signal correlates with the lack of the first fluid in the first conduit;
• and
• providing a first motive force to the first fluid through the first conduit, with the first pump.
