well, since Baskin Robbins having 31% discount today,
and it was Andrew birthday today ,
so we decide go for Baskin Robbins have ice cream today :D
(in fact, it just because there is 31% off of Baskin Robbins today, pity Andrew :P)

After we finish ice cream, there is left unused dry ice.
 hiak hiak, then we have a test with drop some water together with dry ice  :D
lets see what will happen :P
