DIY Rocket Valentines Supplies Needed
You need a few things to make these super-fun Valentine rockets. Luckily you can find them all at the drug store or online. Plus we’ve created a free printable for you to download. Simply fill out the form below to get it emailed to you.
- White card stock or heavy paper
- Mini M&M’s, single size (one tube per Valentine)
- Extra Strength Alka Seltzer tablets (one packet per Valentine)
- Transparent treat bags (one bag per Valentine)
- Ribbon or twine
- DIY Rocket Valentine Printable
Make Your DIY Rocket Valentines
- To make the Valentines, first, print out the DIY Rocket Valentine Printable and fold it in half and then half again. Punch a hole in the upper left corner of the Valentine and feed a ribbon through it. Don’t forget to address and sign the card!
- Place one Mini M&M’s tube and one Alka Seltzer packet into a cellophane bag and tie closed with the ribbon, making sure the Valentine hangs on the front.
How to Make and Fire Your Rocket Valentine
You’ll need the following to assemble your rocket:
- Valentine contents
- Transparent tape
- Glue gun
- Eat your M&M’s :) Break off the cap and set it aside.
- Cut out rocket wrap and tape on the rocket. Cut out the rocket cap, cut a slit along the pink line, and tape it into a cone until the pink line overlaps the pink heart. Glue onto the end of M&M tube opposite the cap.
Now to fire these rockets! Safety first! Wear eye protection before firing a rocket! And FYI, they get a little messy, so be sure to do this outside. Because you will want to fire and repeat over and over again like we did!
- Pour a teaspoon of water into tube. Quickly add 1/2-1 Alka Seltzer tablet, close lid and place on ground.
- Watch the rocket blast off from a safe distance. If there’s still Alka Seltzer left in the tube, you can add a little bit more water and fire again.
Here are a few rockets in action…
The Science Behind the Flight
So what makes these rockets fly? It’s the chemical reaction happening inside the M&M tube. When the Alka Seltzer (otherwise known as sodium bicarbonate, aspirin & citric acid) hits water, the sodium bicarbonate and citric acid dissolve, come into contact, react and create carbon dioxide. The tube lid blows off and the rocket shoots up once the pressure in the tube builds up enough from the carbon dioxide produced in the reaction.
