This Friday, the Chemical Heritage Foundation is hosting an all-day First Friday celebration in honor of Fourth of July weekend.

There are a number of fun, family-friendly activities planned, from learning how to make an exploding foam snake to creating beautiful botanical sun prints.

And as a means of participating in Philadelphia’s July 4th festivities, demonstrator Thomas Twardowski will create a spark fountain.

A great (and free!) way to kick off the holiday weekend.
