A solution which caused a bit of a problem & ended up saving the day. The
problem being that stores couldn't keep any containers of Jumpy on the shelves
because they were, quite literally, jumping & bouncing off under their own
was a liquid, which, when applied to any toy (say the feet of a doll), gave that
toy the ability to bounce on it's own. No batteries, electronics or
strings required. To that end, Jumpy was an amazing success. Even
when Simon used it to escape over the walls of the Russian embassy. But,
once all the components of the liquid were mixed together, whatever container
held it became like a Mexican jumping bean & just as uncontrollable.
re-adjusting his formula, finally deciding that the only way to keep Jumpy
safely on the shelves for purchase was to sell the main components in separate
containers. The customer could then mix as much or as little of the
solution as needed.
