Bubble Gun - the new way to vaccinate people

If the COVID booster shots don't kill people, the "Bubble Gun" may just do the trick. The World Economic Forum just posted this video. The creator hopes to shoot people in the arm painlessly using a laser to heat glass that contains vaccine liquid which will then be injected into people at 100kmh. It will help tackle vaccine hesitancy according to a study done by Gavi which is ran by Bill Gates.
