The Steam Door is a splicable switchable tile which was introduced on Growtopia's 3rd Anniversary during January, 2016. It be toggled on/off by using steam-related items. When toggled on, the item acts as a solid block which players cannot pass while killing all players standing in the way. When toggled off, it opens and acts as a non-solid block which players can walk through.

Possible setup with Steam Door.
