Some color-change skin

A thin layer of makeup or rubber skin that can change colors when power is applied.

Could be very useful for Santa Claus in a mixed people environment. The people wanting pictures with Santa could select the skin color they want on their Santa!

Mobile shower bus

For use at campsites and areas with homelessness. Bus could roll up and offer showers and then a ride to get a day job or interview for other jobs.

Could be a way to reduce disease and offer opportunities to people.

A handshake extender

You could put filled gloves on the end of a couple of PVC pipes sticks and I make Mickey Mouse and so that you can fist bump or shake hands with people in the state of physical distancing to avoid whatever it is the other person has.
