New netting has been installed over the rotunda at the state Capitol.
The new net, which appears to be a clear, fishing line material, means that any balloons released in the Capitol would only be able to raise to the trumpeter's ring rather than floating to the top of the dome.
Red heart balloons have been a frequent sight at the Capitol as of late, and dozens have been released into the dome.
Department of Administration employees have repeatedly voiced concerns that the balloons could damage the "Resources of Wisconsin" painting at the top of the dome, but many protesters have disputed that assertion.
A red heart balloon was at the center of an incident involving a state worker and protester on Monday. That worker was arrested Thursday and faces a tentative charge of endangering public safety after allegedly popping the woman's balloon and pushing her into a door.
