Video transcript

Jellyfish stings are so bad because they inject venom through thousands of microscopic barbs called nematocysts. This venom can cause intense pain, itching, swelling, and in severe cases, difficulty breathing or even heart problems. To alleviate pain, rinse the area with vinegar to neutralize the venom, remove tentacles with tweezers, and immerse the sting in hot water for pain relief.
