Jeden Freitag um 18 Uhr zeigen wir dir bei unserer Tour unseren Maker Space. Es erwarten dich rund 900m2 Werkstattfläche, eine Menge ganz unterschiedlicher Bereiche, viele Maschinen und Geräte. Wir freuen uns auf deinen Besuch!

Join our monthly “Queer Kegelabend”, which is mostly a pure fun event with a slight sportive touch. No previous experience required. Beginners and all genders most welcome! It is our ambition to welcome a broadly diversified crowd! Your own omfortable footwear might contribute to an enjoyable evening. **Schedule:** 1. 19:20 Get together 2. 19:25 Instructions (including safety), line-up of participants 3. 19:30 Getting started * *Latecomers unfortunately can´t be admitted.* * *Please bring a few EUR 1 coins to keep the coin operated machinery going.* There is no drinks or food service in the basement (Kegelbahn) of Café Weidinger. So feel free to order something on arrival and take it downstairs before we get started. Alternatively bring your own drinks or food. Yes, this is possible! Its chatting, meeting (new) people, catching-up with the ones you might already know from our monthly MeetUps at the HIVE or other events. Communication is key, like always. Let’s enjoy a nice evening together with a modest sportive touch on the side! **Please show respect to the others and arrive on time.** As we need to line-up the players before getting starteted, hence late comers unfortunately can´t be admitted. **What is skittles play (Kegeln)?** Skittles play has a very long tradition in Europe and is the game before the Americans "invented" bowling. So we will play with 9 pins and smaller balls with less weight compared to bowling. **Costs:** To rent the skittle alley is just EUR 8 per hour for the whole group. We will divide costs by the number of participants. So expect a contribution of around *EUR 2-3 for the whole evening*. The number of participants is limited. The machinery of the skittle alley is coin operated and accepts EUR 1 coins only. So please bring along a few EUR 1 coins to keep the machinery going! **Participation Fee:** To help cover the Meetup maintenance fee, we recommend a donation of 1-2 Euros directly to the organizers. **Results:** The results of the evening (Igo is so kind to count the scores and enters theses for each participant in a spreadsheet) are published in the "pictures" area of the MeetUp. Historic results are availble there. **Cafe Weidinger** has not been renovated over the last at least 50 years. The skittles alley dates from 1964. You can feel this "special flair". A bit shaby, but inexpensive fun for a whole evening. It´s almost a museum of a skittles alley. **The difference between bowling and skittles play**: * The bowling lanes are covered with an oil film, the skittles lane is not. * In bowling, the ball is is considerably larger and heavier. * Bowling lanes are slightly curved, our lane is flat. * Bowling balls have three holes, our balls have none, one or two. Most of our balls have two holes. * Nine pins are thrown instead of ten. * In bowling, the pins are set up by so-called pin-setter machines and therefore stand freely in contrast to skittles, where the pins hang from strings. * Our skittles lane is an asphalt lane. * You do not need to rent or bring special shoes llike for bowling. But to play in sneakers or sportive footwear is more comfortable.

Welcome Book Lovers! Join our Meet Up Group to find like-minded book readers! This event is for everybody interested in listening or sharing new book content or comment on it. You are welcome just to come for inspiration. You definitely don't need to read books at the moment. It is a gathering for everybody to find like-minded people interested in learning something new. :) Feel free to bring your own book with you. The event will take place at the volunteer organisation MUT. It is an organisation to supports humans, animals and the environment especially in Vienna. I am happy to host it there. MUT or the Social Book Club look forward to some donation to cover the cost of this event. If you would like to help, please bring some cash with you. This is the address: Rechte Wienzeile 37, 1040 Wien Walk until the end of the main entrance hall. At the end of the hallway you find a big green gate with a sign of the Social Book Club. Please give your best to be on time so that we can have a nice introduction round together. If you can't attend anymore please cancel the event to give someone else the space to come. :) For any questions or comments give me a message. Check out the Social Book Club Website for more content: https://socialbookclub.de/ Looking forward to seeing you there! :)

**THIS SHOW IS NOW SOLD OUT (NEXT TRUE STORY NIGHTS 14TH JAN).** The hugely popular TRUE STORY NIGHTS from Vienna Storytelling Collective have a pre-Christmas show December 19th 2025 to continue its 4th year of monthly sold out shows at the grand Volkstheater Rote Bar. These exciting storytelling evenings sell out early at Volkstheater, so we are posting it now (before the line up is finalised) so Vienna Storytelling Collective members don't miss out. We have been bringing you a different line up of performers each month, with surprising, moving, hilarious and sometimes shockingly true stories. Your host as ever is Turan Ali, producer of BBC drama/comedy, who welcomes you to a rollercoaster evening of gripping, high quality true stories – some from Vienna. Our ever-changing quartet of storytellers for each show includes novelists, comedians, radio, TV and film professionals, screenplay writers, performance poets, singer-songwriters and theatre-makers. It feels like being the priest at a confessional, hearing such personal revelations …. but you don’t need to keep all these a secret! WHAT THE AUDIENCES HAVE SAID: “Exhilarating”, “A brilliant evening every time”, “Funny and very moving”, “Incredible stories!” True stories guaranteed to astonish, amuse or amaze you with their honesty. The line-up for our December 19th 2025 TRUE STORY NIGHTS is Turan Ali, Anna Esterbauer, Jacob Liss and Bryan Benner. **Turan Ali** has been producing, directing and writing BBC Radio dramas, comedies and documentaries for 25+ years.

### **,,Wirklich sehen, hören, fühlen – Wie geschärfte Wahrnehmung Nähe ermöglicht''** **Workshop für Sinne, Selbsterkenntnis & Beziehungstiefe** *** **Was, wenn echte Verbindung nicht durch Reden, sondern durch Wahrnehmen beginnt?** Wie nah wir anderen kommen – in Partnerschaft, Freundschaft oder Familie – hängt oft davon ab, **wie klar und fein wir wahrnehmen können**: uns selbst, den anderen, die Situation. In diesem Workshop schulen wir unsere Sinne – **sehen, hören, riechen, fühlen** – und erkennen, was zwischen Wahrnehmung und Reaktion liegt: unsere gelernten Muster, Schutzmechanismen und tiefen Bedürfnisse. *** **Inhalte & Übungen**: * Wie „Wahr“-nehmung funktioniert – und wie sie getäuscht werden kann * Sehen, Hören, Riechen, Fühlen bewusst trainieren – mit alltagsnahen Übungen * Schulz von Thun: Was höre ich wirklich, wenn jemand spricht? * Virginia Satir: Welche Reaktionen schützen mich – und verhindern Nähe? * Karen Horney & Bindungstheorie: Warum wir uns so schwer tun mit Kontakt * Sinneserfahrungen mit Alltagsgegenständen (z. B. Kaffee, Stoffe, Düfte) * Achtsame Selbstwahrnehmung & ehrlicher Austausch in Kleingruppen *** **Warum das wichtig ist:** Viele Kommunikationsprobleme und Beziehungskonflikte entstehen nicht durch bösen Willen – sondern durch **nicht wahrgenommene Signale**, alte Muster oder unbewusste Schutzreaktionen. Wenn wir die Welt feiner spüren lernen, **werden wir echter, weicher, verbindlicher** – ohne uns zu verlieren. *** **Für wen?** Für Menschen, die sich selbst und andere besser verstehen wollen – nicht theoretisch, sondern **im Spüren, Erleben und im echten Kontakt**. *** 📍**Ort:** jeden Sonntag 🕖 **Zeit:** 11:00-14:30 ☕ **Mit Sinnesimpulsen wie Kaffee & Duftübungen** Kaffee & kleine Snacks inklusive! 💶 **Beitrag:** 25€ 📝 **Anmeldung:** über Meetup oder Emailanmeldung unter: orhanberatgueclue@gmail.com

On **Sunday, 21.12.2025**, I am planing a hike in the Lainzer Tiergarten. We meet at the U4 station Hütteldorf, walk through the Nicolaitor and hike to the Hubertuswarte (a lookout tower) on the Kaltbründelberg (508m). We continue to the main entrance, the Lainzer Tor and on another path back via the Nicolaitor to the U4 station Hütteldorf. At Lainzertor there is the possibility to take bus 56B, e.g. to U4 Wien Hietzing. So if you want, you can end the hike at the Lainzer Tor. So there are two hiking options of different lengths: **1\. U4 station Hütteldorf to Lainzer Tor:** Length of the tour: approx. 12km Duration: approx. 3.5h Altitude difference: approx. 300m up and 250m down **2\. U4 station Hütteldorf\, Lainzer Tor to U4 station Hütteldorf \(circular hike\):** Length of the tour: approx. 18km Duration: approx. 5.5h Altitude difference: approx. 500m up and 500m down We **meet at 9 a.m**. outside (and south) of the **U4 station Hütteldorf at the lift at the pedestrian bridge over the Vienna River** (see the photo below). Everyone has to bring their own food and drink (at least 1 liter), as we will not stop for a bite to eat. We take two to three breaks to rest and eat as needed. My hikes and mountain hikes are free of charge and purely private joint leisure events. I am not a certified hiking or mountain guide. Participation is at your own responsibility and risk.
