• Helictites often grow at unusual angles, defying the pull of gravity.
• Scientists study helictites to understand the mineral-rich water flow in caves.
• The formation of helictites requires specific conditions of water saturation and mineral content.
• Photographers are drawn to caves with spectacular helictite formations.
