Some home experiments only stay steady for a few steps.<br /><br />Emma shared footage from Hampshire showing a brother and sister sitting together on a mattress at the top of an indoor staircase.<br /><br />As they start sliding down, the mattress shifts and folds, tipping forward and sending both riders over the front.<br /><br />They tumble onto the floor as the mattress continues to move beneath them.<br /><br />The brief ride turns into a reminder of how quickly a simple setup can change on a staircase.<br /><br />The moment ends as abruptly as it begins.<br />WooGlobe Ref : WGA199711<br />For licensing and to use this video, please email licensing@wooglobe.com
