A fairly common feature of Israeli children's hofa’ot (performances) is the
way overused fresh and original ultraviolet light.
Typically, the young performers don black clothes and put white socks on their hands and shoeless feet. Upon occasion, the kids will then add white belts or scarves to complete the look.
The overhead lights are turned off, and – with the “purple light” shining on the stage – the
captive audience proud and loving parents watch as disembodied white blobs dance in unison before them.
Over the years, I’ve been privileged to see countless renditions of this routine - especially in honor of Chodesh Irgun and also at Chanukah parties in gan.
But it was only today that I learned that an ultraviolet light is known as an ooltra in Hebrew.
And what about the dance itself? According to one of my favorite Heblish-speakers, it’s referred to as “doing an ooltra.” (Sample sentence: “For our rikud (dance), we’re going to do an ooltra.”)
