5 Towns Jewish Times Fifth grade Bais Yaakov girls and Gedolei HaPoskim in Hilchos Shabbos
finally have something very much in common. Both are very much excited
about the new rainbow looms – albeit for quite different reasons. For
the Poskim, finally after all these years, the esoteric malachos of
Maisach, Ossei Shtei Batei Nirim, Oreg and Potzaya, have practical
everyday application that people are actually doing.
But let’s step back a bit to describe the latest craze that has hit
not only the Bais Yaakov’s but even the boys Yeshivos. There are
miniature weaving looms in which colorful rubber bands are fitted onto
and the practitioners of this new pastime are now weaving colorful
rubber band jewelry. [...]
The new craze presents both challenges and opportunity. The
challenges can be divided into three categories. We will go through
each one.
THE FIRST CHALLENGE
One challenge is that entire cadres of young girls and boys are now
unwittingly violating four of the most obscure Av malachos of Shabbos.
Maisach is setting up the loom. In our case it is setting up the
rubber bands on the plastic mini-loom. Other Poskim hold that it is
only when the loom is set up on the horizontal side that Maisach
applies. Regardless, Maisach will be violated when the new jewelry is
being woven.
Oseh batei Nirin in the theory is the setting up of the loom itself.
The loom used in this modern manifestation works differently. It does
not have the back and forth pedals, but according to some of the
explanations found in the Rishonim, the loom used would be a violation
of Oseh Batein Nirim too. Some Poskim hold that the violation of Osei
Batei Nirim involves merely passing the strings through the weaving
machine.
There is also the Malacha of Oreg which is the actual weaving. This
can be violated even without the loom. The Rainbow Loom offers that
possibility too. Indeed, from the fact that there are so many
combinations, each different pattern can be a different violation of the
above three Av Malachos.
The fourth category of prohibited Malacha involving weaving is called
Potzaya. This can involve removing the woven item from the loom, or
removing one of the bands from the total bracelet.
Some would like to argue that because the main material being used is
made of rubber bands, that it is temporary and not a violation of the
weaving Malachos. However, most rishonim understand that temporary
means less than 24 hours. Experience shows that this is definitely not
the case here. [...]
