Yes, a new Italian festival called Festa Italiana Bethlehem is joining Bethlehem's hearty festival lineup this June, set for June 5 and 6 on Main Street.
Lava is made up of crystals, volcanic glass, and bubbles (volcanic gases). As magma gets closer to the surface and cools, it begins to crystallize minerals like olivine and form bubbles of volcanic gases. When lava erupts it is made up of a slush of crystals, liquid, and bubbles.
This type of lava is generated by Basaltic magma, which is very fluid in nature and drives very fluid lava flows once on the surface. This type of magma allows gas to flow readily out of it making explosive eruptions a rather rare phenominon.
