Nature's Squeeze is a drink stand known for their fresh-squeezed juices. Colin just got his first job working there! During his training, he made 4 drinks in 12 minutes. Today is Colin's first shift, and he will work for 90 minutes.

If Colin makes drinks at the same rate, how many drinks will he make today?

If Colin made 4 drinks in 12 minutes during his training, his rate of making drinks is 4 drinks / 12 minutes = <<4/12=0.3333333333333333>>0.33 drinks/minute.

Colin's shift is 90 minutes long, so in that time he will make 0.33 drinks/minute * 90 minutes = <<0.33*90=29.7>>29.7 drinks.
Since Colin can't make a fraction of a drink, he will make 29 drinks today. Answer: \boxed{29}.
