The flight attendant explained why it is necessary to throw a bottle under the bed when checking in

It is impossible to be sure that a hotel room is 100% safe, even if it is located in a quiet area and is locked. Security experts advise always checking a new room. A simple water bottle may be enough to do this.

A flight attendant who often stays in hotels during her work admitted that she does not approach a room without throwing a bottle under the bed. Esther, who works for the Dutch airline KLM, shared an explanation of this hack and other tips on her TikTok channel.

In theory, intruders can easily get into rooms, especially if they are located on the ground floor. An open window or a weak lock can help them enter the room.

The flight attendant urged the audience to always check if there was an intruder under the bed without looking down. To do this, travelers can throw a bottle under the bed, and it should come out the other side.

If the bottle is left under the bed, someone may be hiding there, and it is better not to approach but to lock the room and contact the staff. It's also a good idea to check places behind the curtains, in the bathroom, and in the closet.

Budget hotels and poorer countries may not have sophisticated security systems and high-quality locks, so this life hack can help you avoid dangerous situations.
