Kenapa Perlu Berdiri Di Belakang Garisan Kuning?

Tahukah anda kenapa kita perlu berdiri di belakang garisan kuning ketika kita berada di stesen kereta api aliran ringan atau LRT (Light Rail Transit)?

Apabila LRT bergerak dengan laju, ia akan menghasilkan kawasan yang berhalaju tinggi dan bertekanan rendah di sekeliling badan LRT itu. Jadi sekiranya kita berdiri terlalu hampir dengan LRT yang sedang bergerak, ini boleh menyebabkan tubuh badan kita tertarik kehadapan menghampiri badan LRT yang boleh menyebabkan kecederaan. Konsep sains ini adalah berdasarkan 'Prinsip Bernoulli'.

Garisan kuning telah diukur sebagai tanda aras 'jarak paling selamat' kepada pengguna LRT dari berlakunya kejadian yang tidak diingini. 

Jadi sekiranya anda berada di stesen LRT, pastikan kita SENTIASA berada di belakang garisan kuning. Amalan ini juga boleh dipraktiskan  sekiranya kita sedang menunggu bas di stesen bas.

Petrosains Science Festival FUN CREW Brings Music, Arts & Science into LRT Train

Hooray! Petrosains Science Festival is back, bigger and better this year! So to spread the excitement we decided to get together and bring to you the Petrosains Science Festival FUN CREW! Our FUN CREW gave the public a taste of what this year's festival is all about with a surprise promo in an LRT train! We played music, did some science busking, gave away balloons & flyers and took photos with the unsuspecting but delighted public on the train. Check out the pictures!

Petrosains Science Festival FUN CREW before starting the promo. A total of 60 Petrosains staff and volunteers came out to surprise the public in an LRT train and a few stations.
