If you want to add a snow effect to your slides follow these steps. It’s super easy and the end result is beautiful!
Go to Giphy.com and search for “snow transparent”, choose the GIF you like the most and select it. Go to copy link and get it, once you have it copied to your clipboard, go to your Google Slide and select Insert > Image > By URL and paste the link.
Once the GIF is inserted you can rezise to fit your slide or copy and paste it as many times needed if it looks best that way.
