What does this mean?

Hi everyone! I can't understand the last sentence, particularly the part 'crack one open' .
"Like me, you might have a nice collection of dusty Berlitz phrasebooks hanging out in your garage, left over from your last European vacation. You might even crack one open  (poor choice of phrase by the announcer - crack one open usually applies to a bottle or drink or a food container); anyway it just mean 'open one') to learn to say (unintelligible) mi piace SCIENCE FRIDAY."  'I like Science Friday'

It is an Italian phrase (because it is about bilingual children); I think it is 'mi piace' = I like'

A "Berlitz phrasebook" is a book that contains commonly used phrases in some other languages. I do not know if they are available in other countries, but they are common in the USA and marketed for travellers who will not take the time to actually learn a foreign language before the travelers visit a country.

The "unintelligible" part is in a non-English language. I'm not certain, but I suspect that it is Italian.

The "Crack one open" means that you will find a specific phrasebook for a specific langauge and search for a particular phrase in that phrasebook.
