Move search box to footer

Hello,

I would like to move the search box from my nav to the footer.
I was able to hide it from the nav using this code in my css.

form#searchform.form-search{
display:none;
}

Now, I am not quite sure what to add in the footer.php to get it to reappear. I have try using a search widget in the footer but it does not appear either.

Thanks!
