In Ulpan La-Inyan's Level 3 course, 21-year-old חַגַּי (khah-GAH-ee) tells his date, יִפְעַת (yeef-AHT) all about his trip to Nahal Yehudiya, including the heroic act he performs there.
The word is a bit advanced for Level 3, but יפעת could have said, אֵיזֶה סִפּוּר מְרַתֵּק (EHY-zeh see-POOR me-rah-TEK) - What a fascinating story!
מרתק means fascinating.
