We have been so busy inventing!  Today’s inventions are, clockwise from upper left,

A Hider, Felix L.

It can hide things. It can hide paintings

And a lot of other things too.

Spy Airplane, Quino

It can fly and spy on anyone being mean.

A New Circuit, Felix E.

Collar, for a Dog, Hattie

The dog can hear anything when it

Is wearing it.  It can hear snow and lightning.

And even someone throwing something.

It waxes the floor.
