Kalyna Mazal put gauze pads into a plastic bag, part of a volunteer assembly line at a Maryland, US, middle school that was making emergency medical kits for Ukraine. The lightweight, portable kits, designed by trauma surgeon Dan Olesnicky, can be carried in a pocket or a purse, ready if glass shatters or shrapnel flies. Many of the scouts have family in Ukraine, said Dr. Andrew Demidowich, who leads the Plast DC chapter of the Plast Ukrainian Scouting Organization-USA, and wanted a more tangible way to help. Crafting the medical kits was better than just clicking PayPal over and over, he said. "It's sad that we have to make these," said Kalyna, who is 15. "But this could make a difference." Many Plast chapters have been filling boxes with the kits in recent weeks to be shipped along with other aid for Ukraine.
