+
+      <h2>Description</h2>
+
+      <p>
+        Numbers make up
+        <span class="special">everything</span> in our digital world. They flow around us, invisible like the Force or
+        the Matrix, controlling all our many computer-y devices. Two numbers, in particular:
+        <span class="special">0 and 1</span>. <span class="b i">Off and On</span>. Well, we can tell you this: when
+        there's no coffee in our cup, we're completely OFF our game. But when our mug is full of hot coffee, we're
+        totally ON. And now, with the <span class="keyword">Hot Binary Heat Changing Mug</span>, there's a mug that
+        tells us which state our mug is in. In binary!
+      </p>
+
+      <p>
+        See, the
+        <span class="keyword">Hot Binary Heat Changing Mug</span>
+        looks like just a dark mug with binary numbers all over it. That's its OFF or cold state. Add hot coffee (or any
+        liquid) and a series of digits will turn white. Read them continuously from left to right, and you'll read:
+        <span class="keyword">010010000100111101010100</span>. That's <span class="special">in binary</span>. Of course,
+        your
+        <span class="keyword">Hot Binary Heat Changing Mug</span>
+        could just be paying you a compliment. Cheeky, mug.
+      </p>

+          As you add hot liquids, the binary for "HOT" appears (read from left to right in one line, not two:

+        Hot Binary Heat Changing Mug
+        <span class="keyword">"010010000100111101010100"</span>
+      </h1>
+
+      <img
+        alt="Hot Binary Heat Changing Mug"
+        src="assets/img/thinkgeek_2024_hot_binary_heat_change_mug.gif"

+        id="product_img" />
+
+      <h2>Description</h2>
+
+      <p>
+        Numbers make up
+        <span class="special">everything</span> in our digital world. They flow around us, invisible like the Force or
+        the Matrix, controlling all our many computer-y devices. Two numbers, in particular:
+        <span class="special">0 and 1</span>. <span class="b i">Off and On</span>. Well, we can tell you this: when
+        there's no coffee in our cup, we're completely OFF our game. But when our mug is full of hot coffee, we're
+        totally ON. And now, with the <span class="keyword">Hot Binary Heat Changing Mug</span>, there's a mug that
+        tells us which state our mug is in. In binary!
+      </p>
+
+      <p>
+        See, the
+        <span class="keyword">Hot Binary Heat Changing Mug</span>
+        looks like just a dark mug with binary numbers all over it. That's its OFF or cold state. Add hot coffee (or any
+        liquid) and a series of digits will turn white. Read them continuously from left to right, and you'll read:
+        <span class="keyword">010010000100111101010100</span>. That's <span class="special">in binary</span>. Of course,
+        your
+        <span class="keyword">Hot Binary Heat Changing Mug</span>
+        could just be paying you a compliment. Cheeky, mug.
+      </p>

+
+      <h2>Product Specifications</h2>
+
+      <ul id="product_specification">
+        <li class="keyword">Hot Binary Heat Changing Mug</li>
+        <li>
+          As you add hot liquids, the binary for "HOT" appears (read from left to right in one line, not two:
+          010010000100111101010100)
+        </li>
+        <li>A <span class="keyword">ThinkGeek</span> creation and exclusive!</li>

+        alt="Hot Binary Heat Changing Mug"

+
+      <h2>Description</h2>
+
+      <p>
+        Numbers make up
+        <span class="special">everything</span> in our digital world. They flow around us, invisible like the Force or
+        the Matrix, controlling all our many computer-y devices. Two numbers, in particular:
+        <span class="special">0 and 1</span>. <span class="b i">Off and On</span>. Well, we can tell you this: when
+        there's no coffee in our cup, we're completely OFF our game. But when our mug is full of hot coffee, we're
+        totally ON. And now, with the <span class="keyword">Hot Binary Heat Changing Mug</span>, there's a mug that
+        tells us which state our mug is in. In binary!
+      </p>
+
+      <p>
+        See, the
+        <span class="keyword">Hot Binary Heat Changing Mug</span>
+        looks like just a dark mug with binary numbers all over it. That's its OFF or cold state. Add hot coffee (or any
+        liquid) and a series of digits will turn white. Read them continuously from left to right, and you'll read:
+        <span class="keyword">010010000100111101010100</span>. That's <span class="special">in binary</span>. Of course,
+        your
+        <span class="keyword">Hot Binary Heat Changing Mug</span>
+        could just be paying you a compliment. Cheeky, mug.
+      </p>
