Jul Fire Finger Trend on TikTok: What Happened and the Risks

In November 2024, a TikTok trend that started in Germany pushed teenagers to copy the hand sign of Jul, the Marseille rapper who is one of France’s best-selling artists, with their fingers set on fire, like on one of his album covers. On November 23, 2024, Jul publicly asked his fans to stop. This page explains what happened without showing the stunt, then covers what matters: burn first aid, emergency numbers, how to report on TikTok and advice for parents. The “J” sign without fire is perfectly safe. And if visibility is what you’re after, there are safe ways to grow an account, such as a base of TikTok followers.

What was the Jul fire finger trend?

Jul has a sign every fan knows: a “J” made with his hands. On the cover of his album “Album gratuit, vol. 2”, released in 2016, he makes that sign with flames around his fingers. According to Yahoo News France (November 25, 2024), the fire was most likely added digitally.

In early November 2024, teenagers in Germany started copying the image for real, setting their fingers alight on camera to Jul’s track “En live de Periscope”. The trend crossed the border within days. By mid-November the videos were spreading among French teens too, according to Belgian broadcaster RTBF and Swiss outlet Watson. Several participants later posted videos of their burns to warn others (Watson, November 25, 2024).

We won’t describe how it was done, on purpose: every extra explanation raises the risk of copycats. This report by French news channel BFMTV, posted on November 25, 2024, sums up the story without turning it into a tutorial.

What did Jul tell his fans?

On Saturday, November 23, 2024, Jul posted a message on Instagram. Watson reported his exact words, which translate as: “It makes me happy, but I think it’s a bit dangerous for you! If you could stop, that would help me out.” He also asked his followers to spread the message.

The tone is classic Jul, low-key and free of lecturing. It still carried a lot of weight. French media picked up the appeal the next day, from BFMTV to HugoDécrypte, whose video below was posted on November 25, 2024. A star saying “stop” travels further than any official warning, because the trend was being done in his name.

And since then? We found no major revival of the trend in 2025 or 2026. Most of the original videos are gone: the one quoted in the first French version of this article is no longer available on TikTok. The regular “J” sign, meanwhile, is still everywhere, without fire.

Why is this trend dangerous?

Because fire on skin can’t be controlled. A flame lasts longer than expected and can spread to a sleeve, a curtain or hair, and a burn on the fingers can leave lasting damage to how the hand moves. Watson spotted videos where the fire got completely out of hand for the person filming.

There’s also a fire risk for the whole home: these clips are shot in bedrooms, close to fabric, often with no adult around.

The psychology behind it is well known. TikTok’s Safety Center says so on its online challenges page: adolescence is a phase of exploration, when teens don’t always have the skills to weigh a risk against the wish to be seen. TikTok’s Community Guidelines also ban dangerous challenges.

What to do if someone gets burned

If someone gets burned, these are the steps recommended by the UK’s NHS (page reviewed on March 31, 2026):

1. Put out the fire and move the person away from the heat.
2. Hold the burn under cool running water for 20 minutes, as soon as possible.
3. Remove rings and clothing near the area, unless they’re stuck to the skin.
4. Don’t apply creams, oils or butter, and don’t burst any blisters.
5. Lay cling film loosely over the burn without wrapping it, then get it checked.

Call emergency services right away if the burn is large, deep, on the face, or if you’re unsure: 999 in the UK (or 111 for advice), 911 in the US and Canada, 000 in Australia and 112 anywhere in the EU. With a child, never wait and see.

How to report a dangerous video on TikTok

Reporting a video sends it to moderators for review and can limit its reach. It takes seconds:

1. Press and hold on the video, or tap the “Share” arrow.
2. Choose “Report”.
3. Pick the reason covering dangerous activities and challenges.
4. Submit. The creator won’t know who reported it.

Don’t share the video, even to mock it: every share pushes it toward more accounts. Our guide on how to report a TikTok account goes through each reason and what happens next.

One more useful point from TikTok’s Safety Center: when the platform gets reports about a challenge it investigates, and sometimes it finds no evidence of the trend at all, even while warnings are being shared everywhere. Some “challenges” are hoaxes designed to spread fear. So before passing on an alert, check that a reliable news outlet is covering it, as was the case here.

Parents: how to talk about it with a teen

TikTok suggests a four-step method you can use word for word with your child:

1. Stop: pause on the video.
2. Think: is it safe? Is it real?
3. Decide: if it’s risky, or you’re not sure, don’t do it.
4. Act: report the challenge in the app and don’t share it.

The same page advises against saying “all challenges are dangerous”, because most aren’t and teens know it. It works better to ask why this one appeals to them, then suggest another way to get the same thing: making people laugh, being seen, joining in with friends. For the Jul trend the answer is easy: the “J” sign without fire, set to music, has the same effect.

And if your child already took part? Start by checking their fingers: a burn that looks minor can get infected and deserves a doctor’s or pharmacist’s opinion. Then suggest deleting the video, without shaming them, and replacing it with a fire-free version of the sign. The conversation matters more than the punishment.
