When I first heard about this I thought this was a safety campaign for the summer. However, when I saw this ad I realized that this was nothing of the sort.
For a whole list of Segula ads see The latest סגולה and Some of the segula type ads that I have seen in the past.
I recently heard a drasha from a Charedi Rosh Kollel who decried the whole segula business and he said the following. When Bnei Yisrael fought Amalek the Torah says that when Moshe raised his hands they won and when he lowered them they lost. Chazal asked did Moshe's hand win the battle? The Rosh Kollel said that if we asked this question today about a Gadol (do R' Chaim Kanievsky's raised hands make us win the war?) the answer would be "of course" and "how can you even ask such a question"? Yet, Chazal did ask this and didn't answer of course.
