10 TikTok life hacks we leaned on in 2021

In 2020, TikTok was named the fastest growing app, and in 2021 it had reached over 1 billion users. 

The video sharing platform has content for all viewers, but one major category of viral TikToks is "life hacks." The hashtag #Lifehack has over 53 billion views on TikTok, and these 10 videos made a big impact. 

From cooking to cleaning to technology, we may have leaned on these hacks to live simpler, more organized lives — or at least were entertained while watching.

3. Eliminate bacon grease

Everyone loves bacon in the morning, but getting rid of that bacon grease can be messy. For this hack, you'll just need to put some tinfoil over your sink drain, pour the grease in, and wait for it to harden. Once the grease hardens, you can fold up the tinfoil and throw it away. The grease won't get everywhere or clog your drain.
