Algodoo

"sucertity" isn't a word.

I meant security

Also, it’s misspelled

Okay, no problem. You can correct that by editing the scene. BUT you cannot edit a scene by using the Algodoo built-in browser. You need to use any standard web browser like Chrome, FireFox, and others. After signing in, simply click on the word "Edit" in the upper-right corner of the scene, then make any corrections to the scene or to the scene title, and then upload the corrected scene to Algobox. Easy Peasy!
