The Legend of Zelda: Breath of the Wild Star Fragments

Star Fragments increases the amount of Star Sand earned by 50% within the effective time. Star Fragments typically last for 30 minutes after use, but may last longer during special events. Check the "Today" tab to see what events are happening in the game. You can also use multiple Star Fragments at once to stack their duration up to 24 hours, so you don’t need to use one every 30 minutes.

• Of course you can use them as anti-tangle balls for washing machines (practical)
• Use glow-in-the-dark PLA to achieve a luminous effect!
• Or use it to entertain children.
• Anti-tank. (Practical!)
• Breakwater, also known as weak wave stone. Used to absorb the impact of waves or large water to protect the coast or river embankment.
