Here's a collection of chemistry projects and articles relating to Christmas and other winter holidays. You can make homemade real or artificial snow, holiday ornaments, and gifts and perform seasonal color change demonstrations. 01 of 18 Crystal Snow Globe You could use glitter for a snow globe, but crystals will look more realistic. sot, Getty Images Snow made from water crystals melts at room temperature, but snow made from benzoic acid crystals will still be decorating your snow globe when the weather warms up. Here's how to make a snow globe by precipitating benzoic acid to make the 'snow'. 02 of 18 Make Christmas Tree Preservative Keep your tree alive by adding a preservative to its water that you can make yourself using common household ingredients. Martin Poole, Getty Images A lot of people choose Thanksgiving Day or Thanksgiving weekend as the traditional time to put up the tree. If you want the tree to still have needles by Christmas, you either need a fake tree or else to give the fresh tree a tree preservative to give it the help it needs to make it through the holiday season. Use your chemistry knowledge to make the tree preservative yourself. It's economical and simple. 03 of 18 Poinsettia pH Paper A poinsettia is a natural pH indicator. alohaspirit, Getty Images You can make your own pH paper with any of a number of common garden plants or kitchen ingredients, but poinsettias are common decorative plants around Thanksgiving. Make up some pH paper and then test the acidity of household chemicals. 04 of 18 Make Fake Snow Fake snow is made from sodium polyacrylate, a water-absorbing polymer. Anne Helmenstine You can make fake snow using a common polymer. The fake snow is non-toxic, feels cool to the touch, and looks similar to the real thing. 05 of 18 Colored Fire Pinecones It's easy to make colored fire pinecones. Anne Helmenstine All you need are some pinecones and one easy-to-find ingredient to make pinecones that will burn with colored flames. The pinecones are easy to prepare, plus they can be given as thoughtful gifts.

Cyndi Monaghan / Getty Images Do real snowflakes melt too quickly? Grow a borax snowflake, color it blue if you like, and enjoy the sparkle all year long! Grow a Borax Crystal Snowflake 07 of 18 Snow Ice Cream Recipes This girl is catching snowflakes on her tongue. Somehow I think these snowflakes are fake (ick) but it's a great photo. Digital Vision, Getty Images Actually, you'll get flavored snow slushy unless you apply some freezing point depression to your ice cream-making process. When you make snow ice cream you can use snow and salt to freeze a flavored cream mixture or else you can use ice and salt to freeze actual flavored snow. It's a pretty great family project, either way. 08 of 18 Snowflake Chemistry " Snowflakes" ( CC BY 2.0) by James P. Mann Here are answers to common questions about snowflakes. Learn how snow forms, what shapes snowflakes take, why snow crystals are symmetrical, whether no two snowflakes really are alike, and why snow looks white!

It's easy to find peppermint-scented shaving cream for the winter holidays. Try a floral scent for Valentine's Day. Anne Helmenstine Use a surfactant to marble paper to make your own gift wrap. You can embed a fragrance in the paper, too, so that it can smell like candy canes or Christmas trees. 11 of 18 Make Your Own Snow If the temperature is cold enough, you can make snow yourself!.

Take matters into your own hands and make your own snow. 12 of 18 Does Eating Turkey Make You Sleepy? Chemistry shows it's not the turkey that makes you sleepy after a big dinner!. Last Resort, Getty Images Turkey is a common choice for holiday dinners, yet it seems like everyone feels like taking a nap after eating it. Is the turkey to blame or is there something else making you snoozy? Here's a look at the chemistry behind "tired turkey syndrome."

This is an easy chemistry project that makes a spectacular decoration. 17 of 18 Crystal Holiday Stocking Soak a holiday stocking in crystal solution to make a glittery crystal decoration or ornament. Lucas Allen / Getty Images Soak a holiday stocking in crystal growing solution to get crystals to form on it. This yields a sparkling crystal decoration or ornament that you can use year after year. 18 of 18 Silver Holiday Ornament This silver ornament was made by chemically silvering the inside of a glass ball. Anne Helmenstine Mirror a glass ornament with real silver using this variation of Tollen's reagent. You can coat the inside of a glass ball or a test tube or any other smooth surface to produce a keepsake holiday decoration.
