Do you have control of the HTML mark-up? If so, you could try something like this:
<div class="tricks_head">
<div class="trick">
Lorem ipsum dolor sit amet, consectetur adipisicing elit. Voluptates, totam.
</div>
</div>
<div class="tricks_head">
<div class="trick">
Ratione, maiores labore nulla atque recusandae repellendus est. Iusto, ut.
</div>
</div>
With non-numeric classes for the divs, the JavaScript is fairly simple:
$('.tricks_head').click(function() {
var $tricks_head = $(this);
$tricks_head.find('.trick').toggle('slow');
});
You can see a working demo here: http://jsfiddle.net/codebyren/AqSp2/
