Discover the magic of invisible ink with lemon juice! 🍋 Scouts can write secret messages using a cotton swab dipped in lemon juice. Once dry, reveal the message with a safe heat source, like a hair dryer. The heat turns the acid brown, making the writing visible. This fun activity is perfect for themes like communication, science, or magic. Easy to set up for all ages, but remember: adult supervision is essential during the heating step. #STEM #KidsActivities #CubScouts
