It stunk like somebody dying dozens of eggs,
the children shrieked when the baking soda
plopped into vinegar and the balloons inflated.
He stacked weights on bridge models made of
notebook paper, cardboard and drinking straws,
they cheered loudly as it collapsed and crashed.
“Will it sink, will it float?” with an old fish tank,
“Waves in a Bottle” with cooking oil and water,
amazed at how it always goes back to the top.
They laughed at riddles about the elements,
glued Fruit Loops, Cheerios, and Apple Jacks
on neon colored poster boards to show atoms.
After a week, the water was gone, salt left behind
and it was time for them to put away the books.
