Bose Einstein Condensate is a state of matter like solid, liquid and gas but its atoms don’t act like dots they act like waves. Bose Einstein Condensate is made by using a gas (Helium works best because it is light) and freezing it to nearly 0 Kelvin (-273 degrees Celsius.) If you put it in a jar it will climb out of it! My dad taught me this when I was 4. I told my teacher and she was so impressed she called in the head teacher. Neither of them had heard of this amazing state of matter so they read about it on the Internet. Why don’t you do the same, starting at Wikipedia. If you didn’t understand then watch this video.
