One of the highlights of Silicon Valley is its diverse and multicultural population, which blends harmoniously in all areas of life. More than 3 million people from different parts of the world live in an area slightly smaller than Lviv (121 square kilometers). One area of cultural cooperation is various ethnic events. Ukrainians in Northern California actively participate in such events, promoting Ukrainian culture and national interests.

On August 14, 2021, Ukrainians joined the international Kids Fun Festival in Cupertino, California. As one of the largest children's festivals in Silicon Valley, the Kids Fun Festival annually attracts over 30,000 participants from across the San Francisco Bay Area. This festival is dedicated to children of all ages and ethnic backgrounds and includes fun games, exhibitions, and international delicacies.

Oleg Kernitsky's call on Facebook for help in representing Ukraine at the festival was answered by Iryna Kulchytska and her family (Mykola Zelenyak and daughters Gabriella and Isabella) and Yevhen Yankovsky. In just a few days, they prepared a colorful tent with elements of Ukrainian ethnic and cultural heritage, traditional clothing, and folk music. The volunteers skillfully divided up the tasks, encouraging hundreds of visitors to learn more about Ukraine. It was impressive that they all worked so well together, even though they had never met before.

Yevhen Yankovskyi and Oleg Kernitskyi introduced guests to Ukraine's geographical location, history, and notable places. Since many visitors were from Taiwan, they drew parallels between the historical relations between Russia and Ukraine and the examples of China and Taiwan. Each of them also took care of costumes, souvenirs, postcards, and accessories for the tent.

Iryna Kulchytska and her family actively invited children to make paper toys. Blue and yellow paper fans were especially popular, as they both saved guests from the heat and promoted Ukrainian symbols. The highlight of the tent was a photo zone in the form of an old Ukrainian hut with a thatched roof, woven fence, and sunflowers. Hundreds of visitors took photos wearing Ukrainian wreaths and straw hats, and near the tent they learned the words “hello,” “thank you,” and “goodbye” while dancing to live music.

Valentina Bogdanova, Boris Senik, Dmytro Savitsky, Oksana Tak, and many others came to support their compatriots. Although it was difficult to predict the number of visitors due to fears of COVID-19, the conclusion is clear: such events are extremely important for promoting Ukrainian culture at the everyday level in Silicon Valley. They also help to unite the Ukrainian community around common goals, because the strength of blue and yellow hearts lies in unity.
