Traveling by Electric Scooter on Shabbat

February 1st, 2024|Choleh, Prohibitions, Shabbat, Synagogue, Technology, Tefillah|

QUESTION

Maryland

I have a congregant who can no longer walk to shul. I have discussed the option of using the Grama scooters approved by Zomet and the Star K, but they cost more than $4000. She is able to purchase a “regular” used scooter for only $400. Would the financial savings justify using a regular scooter on Shabbat (perhaps with using a shinuy)?

Do you have any advice for

QUESTION


Chicago, IL

A woman who converted to Judaism under Reform auspices and is married to a Jewish husband is interested in relocating to our neighborhood and will eventually undergo another giyur (conversion) under Orthodox auspices. She does not currently live in our neighborhood and knows that she will not be able to complete her conversion until she moves to the neighborhood.

Until she relocates and converts,

Using “Water Wow!” Toy on Shabbat

December 1st, 2023|Orach Chayim, Prohibitions, Shabbat, Shulchan Arukh, Technology|

QUESTION

Canada

Would it be permissible to use the Water Wow! toy on Shabbat? Assuming that it is, at the very least, uvda d’chol, what are other issues are there?

Here’s a description of how it works:

The basic concept is that each page is “laminated” with a very thin sheet of paper – almost like tissue paper, but more durable. When the paper is moistened by the water in the pen, it becomes see-through and reveals the picture underneath. There’s no chemical reaction involved.

ANSWER

Had it been that the water was interacting with some chemical to create the color, it obviously would be

Food Brought by Car or Without an Eruv on Shabbat

October 29th, 2023|Eiruv, Orach Chayim, Prohibitions, Shabbat|

QUESTION

Israel

There is someone who meets her elderly parents for Shabbat together with her two siblings, who are not religious. Everyone shares the food preparation, and my friend wonders whether she is allowed to eat the food they bring. The food that is being brought is kosher and not cooked on Shabbat, but will be brought in a car on Shabbat or carried through an area without an eruv.

ANSWER

The short answer is, yes, the food may be eaten. In this case, we are dealing with the issue of ma’aseh shabbat when the food was carried without an eruv (or driven), but

QUESTION
Maryland

I work at a nursing home. Like many institutions, during covid we checked temps and asked visitors (and staff) to use an iPad to answer symptom checks as they come in, even on Shabbat. When I come on Shabbat, I have been allowing staff to check my temp with an electronic thermometer and a non-Jewish receptionist ask me the iPad question while s/he enters them in for me. I am trying to make an official policy. Considering the ongoing pikuach nefesh, it would seem unnecessary to require a non-Jew to use

Using an Electronic Based Toilet Training System on Shabbat

April 23rd, 2023|Orach Chayim, Prohibitions, Shabbat, Technology|

QUESTION

Baltimore, MD

There is a family who is using a nighttime toilet training program for their 9-year-old son. The program requires a magnetic sensor that triggers an alarm system. The alarm needs to be turned off and reset when it goes off. What options do they have to continue to use the system on Shabbat? They are concerned that stopping will break up the continuity of his toilet training.

ANSWER

I think it’s fine with a shinuy. I think bedwetting issues can be a source of a lot of psychic angst for

Pushing Someone in a Wheelchair to Shul on Shabbat without an Eruv

March 5th, 2023|Amirah LeGoy, Disabilities, Orach Chayim, Prohibitions, Shabbat|

QUESTION

Jerusalem, IL

Rav Moshe Feinstein (Igrot Moshe OH 4:90) writes that in a place where there is no eruv, a person can only propel themselves or be pushed in a wheelchair by a non-Jew. We are dealing with a case of someone about whom it is not clear if they can walk on their own. Is there room for a Jew to push this person to shul?

ANSWER

If you can do it with a shinuy, or have two people pushing, then it’s shevut d’shevut be’makom mitzvah (a Rabbinic prohibition coupled with another Rabbinic prohibition which is permissible for the sake of a

February 21st, 2023|Orach Chayim, Prohibitions, Shabbat|

QUESTION

Chicago, IL

There is a fancy board game that makes use of a sand timer to limit the time in play (similar to how a chess clock measures the total time in play over the course of the game). Is it permissible to play this game on Shabbat? (What about chess clocks?) Nothing is being measured (30 seconds, 2 minutes), but the sand clock determines the duration of the game.

ANSWER

Although there is a general

Non-Jew Warming Fully Cooked, Dry food in an Oven on Shabbat For Kiddush

January 16th, 2023|Amirah LeGoy, Bishul, Kiddush, Seudah, Havdalah, Orach Chayim, Prohibitions, Shabbat|

QUESTION

PHILADELPHIA, PA

Shalom Rav Linzer – what are your thoughts on a gentile putting dry food to warm in an oven for kiddush? I know it’s not usually done but it seems like a d’rabbanan l’tzorech rabim (rabbinic prohibition done for the sake of the community)? The venue my shul meets at (a conservative synagogue) feels that hot plates are a liability.

ANSWER

This is exactly the case dealt with in SA OH 253:5
