Insulated Cup Design

Design a cup that keeps drinks warm for longer! 🥤 Pick materials, wall structures, outer wraps, and lids, pour in 90°C water 🌡️ and check the temperature after 20 minutes. Watch the cooling curve appear right before your eyes! 📊 The "Heat Leak" tab shows if heat escapes through the sides or top — you'll discover that spending big on walls won't help without a lid! 🎯 Hit the target temperature within budget across 5 mission stages. Expensive materials aren't always best! Supports 7 languages.
