Students of the Christelijk Lyceum school in Veenendaal filled their school with 21,400 cups filled to the brim with water as an exam prank on Thursday morning. A video of the prank posted on Dutch video site Dumpert has been viewed nearly 207 thousand times.

"The exam pupils arrived at at school at half past five. Together with the concierge they filled the cups and put them down", the school's communication assistant Annet Dankelman said to the Gelderlander. 

Other students and teachers had to walk very carefully to avoid making a mess. Most appreciated the stunt. "Many teachers talk about a creative exam prank", Dankelman said to the newspaper.

The students cleaned up their prank themselves, according to the Gelderlander.
